A voltage amplifier operated from a 12 volt battery has a collector load `6 k Omega`. Calculate the maximum collector current in the circuit.

A bulb rated 12 V, 24 W operates on a 12 volt battery for 20 minutes. Calculate : the current flowing through it,

For a common emitter amplifier current gain = 50 if the emitter current is 6.6 mA. Calculate the collector and base current.

The collector supply voltage is 6 V and the voltage drop across a resistor of 600 Omega in the collector circuit is 0.6 V, in a circuit of a transistor connected in common emitter mode. What is the base current if the current gain is 20?

In a CE transistor amplifier, the audio signal voltage across the collector resistance of 2 k Omega is 2 V . If the base resistance is 1 k Omega and the current amplification of the transistor is 100 , the input signal voltage is

An NPN transistor is used in common emitter configuration as an amplifier with 1k Omega load resistance. Signal voltage of 10 mV is applied a across the base-emitter. This produces a 3 mA change in the collector current and 15 mu A change in the base currect of the amplifier. The input resistance and voltage gain are :
