A: A transistor needs a bias or voltage to operate in a linear region unfortunately that is detrimental to gain so by bypassing this emitter voltage the AC gain can be improved.

What is the function of a bypass capacitor in an amplifier?
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
What is the use of capacitors in fire alarm circuit?
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
What is the function of an amplifier in electronic communications?
An amplifier is used to increase the strength of the signal.
What is the amplifier?
An amplifier is an electronic device used to increase the amplitude of electrical signals in sound production.
When capacitors are used to shunt current across components such as resistors they are called?
A capacitor is typically placed across a resistor for the purpose of shunting either the AC component of a current (as in a transistor amplifier) or transient AC 'spikes', and is referred to as a "bypass capacitor".
What is the definition of ultracapacitator?
Ultra capacitors are also called "super capacitors." They are used in myriad electronic circuits and in electric and hybrid cars.
Is paper capacitor use in transistor amplifier?
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
What is amplifier and oscillator?
amplifier is electronic circuit which is used to increase the amplitude of the input signal without affecting its frequency and phase.
What are the electronic devices that are used in electronic design?
OscilloscopeLogic AnalyzerMicroprocessor debug emulator (if microprocessor is used)additional standard misc. electronic troubleshooting tools
Should the capacitors used in electronic circuits have a minimum voltage rating of 25 volts?
Capacitors used in electronic circuits need not have a minimum voltage rating of 25 volts. Electronic circuits powered by batteries at 12 volts and below should work fine with capacitors rated at 15 volts.
What is ment by amplifier?
The official definition of the word amplifier is "an electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction."
What is the electronic device that's used to increase the strength of the signal fed into it called?
Amplifier
