MCQ
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 $h$ is
- ✓$82$
- B$83$
- C$8.2$
- D$8.3$
✓
Answer
Correct option: A.
$82$
$h_{f e}=\left(\frac{\Delta i_c}{\Delta i_b}\right)_{V_{c e}}=\frac{8.2}{8.3-8.2}=82$
