365521 The \(dc\) common emitter current gain of a \(n\) - \(p\) - \(n\) transistor is 50. The potential difference applied across the collector and emitter of a transistor used in \(CE\) configuration is \({V_{CE}} = 2V\). If the collector resistance \({R_C} = 4k\Omega \), the base current \(\left( {{I_B}} \right)\) and the collector current \(\left( {{I_C}} \right)\) are

1 \({I_B} = 10\mu A,{I_C} = 0.5mA\)
2 \({I_B} = 0.5\mu A,{I_C} = 10mA\)
3 \({I_B} = 5\mu A,{I_C} = 1mA\)
4 \({I_B} = 1\mu A,{I_C} = 0.5mA\)
