A piece of semiconductor is connected in series in an electric circuit. On increasing the temperature, the current in the circuit will

In a common emitter amplifier configuration, the current gain is 62 . The collector resistance and input resistance are $5 \mathrm{k} \Omega$ and $500 \Omega$ respectively. If the input voltage is 0.01 V , the output voltage will be

The logic gate for which the output goes 'HIGH' or ' 1 ' only when an odd number of 'HIGH' or ' 1 ' are at its input, is

To get output of the following logic circuit as ' 0 ' (zero), the inputs $A, B, C$ should NOT be, respectively,
