Question

A n-p-n transistor is connected in common emitter configuration (see figure) in which collector voltage drop across load resistance (800 ΩΩ) connected to the collector circuit is 0.8 V. The collector current is

(1) 0.2 mA 

(2) 2 mA 

(3) 0.1 mA 

(4) 1 mA

Answer 1

Ans: (4) 1 mA

Sol. Voltage drop across load resistance, 

VL = ICRC 

0.8 = IC × 800 

IC = 1 mA
