Exercise 1

A $220 \mathrm{V}$ A.C. supply is connected between points $A$ and $B$ as shown in figure what will be the potential difference $V$ across the capacitor?

In adjoining figure, the input $\left(\mathrm{A}.\mathrm{C}.\right)$ is across the terminals $A$ and $C$  and the output is across $B$ and $D$. Then output is

The principle in which a solar cell operates

Conversion of light energy into electrical energy is achieved in a

If the distance of $100 \mathrm{W}$ bulb is increased from a photocell, then the saturation current in the photocell varies with distance$d$ as

In $\mathrm{p}-\mathrm{n}$ junction solar cell, the value of photo -electromotive force produced by monochromatic light is proportional to the

A light-emitting diode has a voltage drop of $2 \mathrm{V}$ across it and passes a current of $10 \mathrm{\mu A}.$ when it operates with a $6 \mathrm{V}$ battery through a limiting resistor $R,$ the value of $R$ is

Transfer characteristics [output voltage $\left(V_0\right)$ vs input voltage $\left(V_i\right)$] for a base biased transistor in $CE$ configuration is as shown in the figure. For using transistor as a switch, it is used
