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 ----------.

The value of power dissipated across the Zener diode ( Vz = 15V) connected in the circuit as shown in the figure is x x10-1 watt. The value of x, to the nearest integer, is--------.

 

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

Consider the following statements A and B and identify the correct answer:

A. For a solar-cell, the I-V characteristics lies in the IV quadrant of the given graph.

B. In a reverse biased  $pn$ junction diode, the current measured in $\left(\mu A\right)$ , is due to majority charge carriers.

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:

Choose the correct waveform that can represent the voltage across R of the following circuit, assuming the diode is ideal one:

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:
