C_3H_9N cannot represent

In an n-p-n transistor, the emitter current is

In n-p-n transistor, the p- type crystal acts as

The dc common emitter current gain of a n-p-n transistor is 50. The potential difference applied across the collector and emitter of a transistor used in CE configuration is, V_(CE) = 2 V. If the collector resistance, R_C = 4 kOmega , the base current (I_B) and the collector current (I_C) are

What is bi-polar junction transistor? Draw the symbol.

In the common emitter configuration of n-p-n transistor, 10^10 electrons enter the emitter in 1 mu s and 2% of the electrons are lost to the base. The current gain of the amplifier is

Symbolically LED is represented as
