For A Common Base Transistor Circuit, The Emitter-current And The Collector-current Are 1 MA And 0.96 MA Respectively. Calculate The Current Gain And Base Current.

The depletion layer in the p-n junction is formed by

When a forward bias is applied to a p-n junction, it :

The resistance of a forward-biased p-n junction is :

When a semiconductor device is connected with a battery and a resistance in series, a current flows in the circuit. The current almost vanishes if the polarity of the battery is reversed. The device may be :

The circuit contains two diodes, each with a forward resistance of  and with infinite backward resistance. If the battery voltage is 6 V, the current through the  resistance is  

Two identical p-n junction may be connected in series with a battery in three ways. The potential drops across the two p-n junction are equal in :

In case of p-n junction diode at high reverse-bias, the current rises sharply. The value of reverse bias is known as : 

A junction diode can be used for :

A p-n junction diode cannot be used :

The current gain for common-emitter amplifier is 59. If the emitter-current is 6.0 mA, find (i) base-current, and (ii) collector-current.
