Question

5 bulbs are connected in series in a room. One bulb is fused. It is removed and remaining 4 bulbs are again connected in series to the same circuit. What will be the effect on the following physical quantities? (Increases, Decreases, Remain Same).

1. Resistance
2. Intensity of light

Answer 1

1. When one lightbulb is removed, the circuit's overall resistance falls because the equivalent resistance in a series is equal to the sum of all the resistances.
2. More current will flow through the circuit, and the light's intensity will rise as the electric circuit's resistance falls.
