While a collector to emitter voltage is constant in a transistor, the collector current changes by 8.2 mA when the emitter current changes by 8.3 mA. The value of forward current ratio hfe is

A

82

B

83

C

8.2

D

8.3

Answer

82

Explanation

Solution

hfe=(ΔicΔib)Vce=8.28.38.2=82h_{fe} = \left( \frac{\Delta i_{c}}{\Delta i_{b}} \right)_{V_{ce}} = \frac{8.2}{8.3 - 8.2} = 82
