The potential difference across the coll...

The potential difference across the collector of a transistor, used in common emitter mode is `1.5V`, with the collector resistance of `3 kOmega`. Find (i) the emitter current and (ii) the base current, if d.c. gain of the transistor is 50.

Text Solution

Verified by Experts

`I_(c)=V_(CE)/R_(L)=1.5/(3xx10^(3))=0.50xx10^(-3)A=0.50mA`
`I_(b)=(I_(c))/(beta)=(0.50mA)/50=0.01mA`
`I_(e)=I_(c)+I_(b)=0.50+0.01=0.51mA`
