A transistor is connected in common emitter configuration. The collector supply is 8V and the voltage drop across a resistor of `800Omega` in the collector circuit is 0.5 V. If the current gain factor `(alpha)` is 0.96, find the base current.

Text Solution

Verified by Experts

`I_c=V_(L)/R_(L)=0.5/800=5/8mA`
`I_c=I_(e)-I_c=I_c/alpha-I_c=I_c(1/alpha-1)`
`=5/8(1/0.96-1)=0.026mA`
