Question

In a npn transistor how the output characteristics can be used to find out current gain in the circuit

Answer 1

Then, the collector or output characteristics curves for Common Emitter NPN Transistors can be used to predict the Collector current, Ic , when given Vce and the Base current

Answer 2

Explanation:

npn transistor work as a amplifiar.

Its use in soundbox....radio...etc

.If input current increase so output voltage increse.

At the point when input and output current go ing to reverse bias.

Thats called cut of area.
