What is an oscillator ? With the help of circuit diagram explain theprinciple and working of transistor as an oscillatoris common emitter configuration, showing how feedback is accomplished by inductive

define the trans-conductance of a transistor.

What is an amplifier ? Draw a circuit diagram for an amplifier withPNP transistor in common emitter configuration. Also define current gain, voltage gain and power gain for it.

Define resistance of conductor. Also give its units

Define resistance and give its units?

Draw a circuit diagram for use of NPN trnasistor as an amplifier in common emitter configuration. The input resitance of transistor is 1000 Omega . On changing its base current by 10muA , the collector current is increased by 2mA. If the load resistance 5k Omega is used in the circuit, calculate the voltage gain of amplifier.

Define specific resistance and state its unit?
