In the circuit shown in Fig. 7.45,

The following diagram (Fig) shows four circuits A, B, C and D. Each circuit has a cell and a torch bulb. Name the circuits in which the bulb will glow? Give reason to your answer.

In the circuit diagram, all the bulbs are identical. Which bulb will be the brightest?

A capacitor C, a variable resistor R and a bulb B are connected in series to the ac mains in circuits as shown if Fig. The bulb glows with some brightness. How will the glow of the bulb change if (i) a dielectric slab is introduced between the plates of the capacitor, keeping resistance T to be the same, (ii) the resistance R to be the same, (ii) the resistance R is increased keeping the same capacitance.
