Your email address will not be published. soon. This type of capacitor is mostly used in household water pumps, Fans, air conditioner and many devices which need at least two phases to work. View Answer, 4. This type of capacitor is sensitive about their polarity and can be only used in DC systems and networks. The capacitor is a two terminal electrical device used to store electrical energy in the form of electric field between the two plates.

c) fixed bias This change is almost the same in collector current because of the transmitter action. Inside the capacitor the terminals connected with the two metal plates separated by dielectric material (such as waxed paper, mica, and ceramic), that separate the plates and allows them to hold opposite electrical charges maintaining electrical field.

What Happens When an AC Line Touches a DC Line? When you connect the capacitors in series the total capacitance is decreased. a capacitor, transformer etc.)

is done on EduRev Study Group by Electrical Engineering (EE) Students. The two transistor amplifier offers a reasonably high impedance while providing a low output impedance. Also, the charge stored by plate of capacitor will be same because it is coming from the adjacent capacitor’s plate. You can study other questions, MCQs, videos and tests for Electrical Engineering (EE) on EduRev and even discuss your questions like Rather we use a multistage amplifier i.e. The state amplifier has no input is not called ______________ Basically, it delivers the reactive power which was previously traveled from the power system, hence it reduces the losses and improves the efficiency of the system. Apart from being the largest Electrical Engineering (EE) community, EduRev has the largest solved In the collector circuit, a load resistor RC of high value is connected. Capacitor bank is installed after a precise calculation. Can you explain this answer? It opposes the change of voltage. of capacitor connected in series.

And, when you connect a capacitor across an AC source, it charges and discharges continuously, due to continuous change in the voltage levels. output of first stage is connected to the input of the second stage through a suitable coupling device and so on. Operation of the Circuit: Let at least one out of the various inputs to the AND gate be low (in 0 state).

c) It is used to provide the quiescent collector current EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. In a simple way, a capacitor also work as a small rechargeable battery. The gate-source capacitance Cgs and gate-drain capacitance Cgd in the diagram below are determined by the capacitance of the gate oxide film. d) To increase input impedance L23 : Transistor Circuit Configuration - Semiconductors, Physics, Class 12, Input and Output Characteristics of transistor in CB configuration, Analysis Of a Transistor Amplifier Circuit Using H-Parameters, L26 : Open Circuit Problem - Capacitor & Capacitance, Physics, Class 12, GATE Notes & Videos for Electrical Engineering, Basic Electronics Engineering for SSC JE (Technical). here is complete set of 1000+ Multiple Choice Questions and Answers, Prev - Analog Circuits Questions and Answers – Transistor Switching Network, Next - Analog Circuits Questions and Answers – Hybrid Equivalent Model, Analog Circuits Questions and Answers – Transistor Switching Network, AVR Microcontroller Questions and Answers – LCD Interfacing, Electrical Machines Questions and Answers, Instrumentation Transducers Questions and Answers, Microwave Engineering Questions and Answers, Electrical Measurements Questions and Answers, Basic Electrical Engineering Questions and Answers, Analog Communications Questions and Answers, Linear Integrated Circuits Questions and Answers, Electronic Devices and Circuits Questions and Answers, Analog Circuits Questions and Answers – MOSFET Amplifier with CS Configuration – 1, Electronic Devices and Circuits Questions and Answers – Biasing Parameters, Linear Integrated Circuit Questions and Answers – Operational Amplifier Internal Circuit – 1. which are insulators), which is used to increase the capacitance of the capacitor. the capacitance is the ability of a capacitor to stores the charge into it. In series no capacitor is directly connected to the source. i am studying on how to eliminate or reduce voltage ripples after rectification this article has enlightened me to search on RC filters in more detail. These two plates are separated by a dielectric material (such as mica, paper, glass, etc. View Answer. Also, if you see the phasor diagram of an ideal AC capacitor circuit you can observe that, current leads the voltage by 90⁰. Why AC Needs More Insulation Than DC at Same Voltage Level? AC or DC – Which One is More Dangerous And Why ? In DC Circuit, the capacitor charges slowly, until the charging voltage of a capacitor is equal to the supply voltage. <>stream Whenever voltage is applied across its terminals, (Also known as charging of a capacitor) current start to flow and continue to travel until the voltage across both the negative and positive (Anode and Cathode) plates become equal to the voltage of the source (Applied Voltage).

View Answer, 6. Thank you author, I think there is a small mistake at the end. Question bank for Electrical Engineering (EE). a) emitter bias Input resistance, Ri=ΔVBEΔIB Where Ri = input resistance, VBE = base-emitter voltage, and IB= base current. Save my name, email, and website in this browser for the next time I comment.

| EduRev Electrical Engineering (EE) Question is disucussed on EduRev … c) To increase gain The DC voltage VEE is applied to the input circuit along with the input signal to achieve the amplification.

Transition capacitance and Diffusion capacitance, Transistor as an amplifier | npn transistor, GATE Notes & Videos for Electrical Engineering, Basic Electronics Engineering for SSC JE (Technical). In a DC Circuit, the capacitor once charged with the applied voltage acts as an open switch. Required fields are marked *, All about Electrical & Electronics Engineering & Technology. Now, you can find the capacitance of the circuit, by using the above formula. over here on EduRev! The electrical equivalent symbol of different types of capacitor is given below: Now, we know the concept of the capacitor’s charging and its structure but, do you know what Capacitance is? The Non Polar capacitors can be used in both AC and DC systems. What Happens to the Battery with Reverse Polarity Wiring Connection. Oct 23,2020 - What is the role of input capacitance in the transistor amplifying circuita)To prevent input variation from reaching outputb)To prevent DC content in the input from reaching transistorc)There isn’t any role for input capacitanced)To increase input impedanceCorrect answer is option 'B'. The Questions and How To Calculate Your Electricity Bill.

Apart from being the largest Electrical Engineering (EE) community, EduRev has the largest solved How to Find The Suitable Size of Cable & Wire for Electrical Wiring Installation? are solved by group of students and teacher of Electrical Engineering (EE), which is also the largest student Now, we will calculate the capacitive reactance in AC circuit. Thus, a weak signal (0.1V) applied to the input circuit appears in the amplified form (10V) in the collector circuit. There are lots of advantages of power factor improvement. The input signal or weak signal is applied across the emitter base and the output is obtained to the load resistor RC  which is connected in the collector circuit. Now, we know the concept of the capacitor’s charging and its structure but, We will not go in detail because our basic purpose of this discussion is to explain the, Now, for finding the value of capacitance of the above circuit, we will apply, Capacitors are used in transformer less power supplies. Difference Between Voltage Amplifier and Power Amplifier, Common Base Connection (CB Configuration), Two Wattmeter Method of Power Measurement, Difference Between Physical and Chemical Change, Difference Between Alpha, Beta and Gamma Particles, Difference Between Electrolytes and Nonelectrolytes, Difference Between Electromagnetic Wave and Matter Wave, Difference Between Kinetics and Kinematics, Difference Between Synchronous and Asynchronous Counter, Difference Between Analog and Digital Signals, Difference Between Stationary and Progressive Waves, Difference Between Positive and Negative Feedback. Its value is calculated precisely and depends on the system voltage and the demand load current. Coupling Capacitor.
