What effect does adjusting the tension on the belt have on the amperage draw of the motor in a system?

  1. No effect

  2. Decreases the amperage draw

  3. Increases the amperage draw

  4. Causes the motor to stop

The correct answer is: No effect

Adjusting the tension on the belt has no effect on the amperage draw of the motor in a system. This is because the tension of the belt does not directly affect the power or electrical consumption of the motor. The amperage draw of a motor is determined by the load it is powering and the voltage supplied, not by the tension of the belt. Options B and C are incorrect as they suggest an increase or decrease in amperage, which is not affected by the belt tension. Option D is incorrect as it implies that adjusting the tension on the belt will cause the motor to stop, which is not the case. Therefore, option A is the correct answer as it states that there is no effect on the amperage draw when adjusting the belt tension.
