Final answer:
A starter motor is used to increase speed and provide torque to crank an engine. It draws a large current from a battery hookup and supplies the energy needed to start the engine.
Step-by-step explanation:
The purpose of a starter motor is to increase starter motor speed and provide the torque multiplication necessary to crank an engine. Starter motors are used in vehicles such as cars and trucks to initiate the engine's combustion process. They draw a large current from a battery hookup to supply the large amount of energy needed to start the engine. In the given scenario, a large truck draws 250 A of current from a 24.0-V battery hookup, and the power supplied to the starter motor can be calculated using the formula:
Power = Current x Voltage
Therefore, the power supplied to the starter motor is:
Power = 250 A x 24.0 V = 6000 Watts
