In a silicon transistor, a change of 7.98 mA in the emitter-current produces a change of 7.8 mA in the collector-current. Find the required change in the base current to produce an equivalent change in the collector current. 


Correct option is

By definition  



                      = 0.9886.  



Again, by definition  




                      = 0.09 mA




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 :


p-n junction diode cannot be used :


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


Calculate the current gain  of a transistor if the current-gain  is 0.98.


A common-emitter transistor amplifier has a current gain of 50. The collector resistance is  and the input resistance is , calculate the output voltage if input voltage is 0.01 V.
