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). |
- Resistance
- Intensity of light

उत्तर
- 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.
- More current will flow through the circuit, and the light's intensity will rise as the electric circuit's resistance falls.
