A lamp is connected in series with a capacitor.
Predict your observations when the system is
connected rst across a dc and then an ac source.
What happens in each case if the capacitance of
the capacitor is reduced?

When dc source is connected, the condenser is charged but no current flows in the circuit. Therefore, the lamp does not glow. No change occurs even when capacitance of capacitor is reduced. <br> When ac source is connected, the capacitor <br> offers capacitative reactance
. The <br> current flows in the circuit and the lamp glows. On reducing C,
increases. Therefore, glow of the bulb reduces.
