While a collector to emitter voltage is constant in a transistor, the collector current changes by 8.2 \mathrm{~mA} when|the emitter current changes by 8.3 \mathrm{~mA}. The value of forward current ratio \mathrm{h_{f e}} is

Option: 1

82


Option: 2

83


Option: 3

8.2


Option: 4

8.3

\mathrm{h_{f e}=\left(\frac{\Delta i_c}{\Delta i_b}\right)_{V_{c e}}=\frac{8.2}{8.3-8.2}=82}

Hence option 1 is correct.
