Semiconductor E...

The conductivity of a semi conductor can be increased by:

A Zener diode having break-down voltage $$5.6V$$ is connected in reverse bias with a battery of emf $$10V$$ and a resistance of $$100\Omega$$ in series. The current flowing through the Zener is

A NOR gate and a NAND gate are connected as shown in the figure. Two different sets of inputs are given to this set up. In the first case, the input to the gates are A=0, B=0, C=0. In the second case, the inputs are A=1, B=0, C=1. The output D in the first case and second case respectively are

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

In a n - type semi conductors which of the following statement is true:

Insulators are materials having an electrical conductivity equal to:

The given truth table is for

Fill in the blank.

A proper combination of $$3$$ NOT and $$1$$ AND gates is shown. If $$A=0$$, $$B=1$$, $$C=1$$ then the output of this combination is
