Which among the following constitutes the major load for an automobile battery ?

Brake light
Self starter
Parking lights
Spark plugs

The correct answer is B. Self starter.

The self starter is the largest load on an automobile battery. It requires a large amount of current to start the engine, and this can drain the battery quickly if it is not in good condition.

The other options are all relatively small loads on the battery. Brake lights, parking lights, and spark plugs all require a small amount of current to operate.

Here is a more detailed explanation of each option:

  • Brake lights: Brake lights are turned on when the driver presses the brake pedal. They are used to warn other drivers that the car is slowing down or stopping. Brake lights require a small amount of current to operate.
  • Parking lights: Parking lights are turned on when the car is parked. They are used to make the car visible to other drivers at night. Parking lights require a small amount of current to operate.
  • Spark plugs: Spark plugs are used to ignite the air-fuel mixture in the engine. They require a small amount of current to operate.
  • Self starter: The self starter is used to start the engine. It requires a large amount of current to turn the engine over. The self starter is the largest load on an automobile battery.
