Lights of a car become dim when the starter is operated. Why?

Options

A. Increases
B. Decreases
C. Remains same
D. First increases then decreases

Answer

### Step-by-Step Solution:

1. **Understanding the Components**:
- In a car, the battery provides electrical energy to various components, including the lights and the starter motor.
- The starter motor is responsible for starting the engine and requires a significant amount of current to operate.

2. **Current Division**:
- When the starter motor is activated, it draws a large amount of current from the battery.
- The total current supplied by the battery is divided between the starter motor and the car lights.

3. **Effect of High Current Demand**:
- The starter motor, when engaged, requires a substantial amount of current, which can be several times greater than what the lights typically need.
- This high demand for current causes a reduction in the amount of current available to the lights.

4. **Potential Drop**:
- As the starter motor draws a large current, there is a potential drop across the battery and the wiring due to internal resistance.
- This drop in voltage means that the lights receive less voltage than they normally would.

5. **Resulting Dim Lights**:
- With reduced voltage reaching the lights, they cannot operate at their full brightness, resulting in dim lights.
- Therefore, when the starter is operated, the lights of the car become dim due to the increased current draw by the starter motor.

### Conclusion:
The lights of a car become dim when the starter is operated because the starter motor draws a large amount of current, which reduces the voltage available to the lights due to potential drop across the battery and wiring.
