Semiconductor Devices Overview

In the CB mode of a transistor, when the collector voltage is changed by 0.5 volt. The collector current changes by 0.05 mA The output resistance will be

For the transistor circuit shown below, if $\beta =100$ , voltage drop between emine r and base is 0.7 V then value of $V_{Cl}$  will be

 The charge on a hole is equal to the charge of

An npn transistor operates as a common emitter amplifier with a power gain of 10?. The input circuit resistance is 100Ω and the output load resistance is 10kΩ. The common emitter current gain 'β' will be -----------. (Round off to the Nearest Integer)

With increasing biasing voltage of a photodiode, the photocurrent magnitude:

Boolean relation at the output state-Y for the following circuits is:

In the logic circuit shown in the figure, if input A and B are 0 to 1 respectively, then output at Y would be ‘x’.

The value of x is ----------.

If an emitter current is changed by 4mA, the collector current changes by 3.5mA. The value of b will be:

In the following logic circuit the sequence of the inputs A, B are (0, 0), (0, 1), (1, 0) and (1, 1). The output Y for this sequence will be:

In the circuit, the logical value of A = 1 or B = 1 when potential at A or B is 5 V and the logical value of A = 0 or B = 0 when potential at A or B is 0 V. The truth table of the given circuit will be:
