An n-p-n transistor at room temperature has its emitter disconnected. A voltage of 5 V is applied between collector and base. With collector positive, a current of 0.3 μA flows. When the base is disconnected and the same voltage is applied between collector and emitter, the current is found to be 25 µA. Find and a, IE, Ip when collector current is 1 mA.

An n-p-n transistor at room temperature has its emitter
disconnected. A voltage of 5 V is applied between collector
and base. With collector positive, a current of 0.3 μA flows.
When the base is disconnected and the same voltage is
applied between collector and emitter, the current is found
to be 25 µA. Find and a, IE, Ip when collector current is 1
mA.
