Input and output signal of an amplifier in `CE` configuration are always

Phase angle between input and output signals in a CE amplifier in degrees is

Draw a circuit diagram of a transistor amplifier in CE configuration. Define the terms (i) Input resistance and (ii) Current amplification factor. How are these determined using input and output characteristics?

Draw the circuit arrangement for studying the input and output characteristics of n-p-n transitor in CE configuration.

What is meant by input and output resistance of a transistor amplifier in CE mode?

Show the circuit arrangement for studying the input and output characteristics of a n-p-n transistor in CE configuration.

Outline the method of drawing input and output characteristics with a neat labelled diagram of an N-P-N transistor in CE configuration.

Oscillator is a circuit that generates signals of de sired frequencies and an amplifier is used to amplify the signals.When transister is used as an amplifier, common emitter configuration is used. Why?

What are the input and output resistance of a transistor in its CE mode?
