Question : 125 of 200

Marks: +1, -0

Determine the supply current in the given network. Take the voltage drop during the forward biased condition is 0.3 V.

Solution:

Voltage drop during the forward biased condition = 0.3 V i.e. Knee voltage
The given circuit can be redrawn as

\I ={12-0.3}/{2+4}={11.7}/{6} \A

∴ Supply current

\I={11.7}/{6} \A
