Final answer:
The modern cranking circuit in an automotive system consists of a battery, starter motor, solenoid, ignition switch, and wiring.
Step-by-step explanation:
The modern cranking circuit in an automotive system consists of five main components:
- Battery: It provides the electrical power needed to start the engine. The battery stores energy in chemical form, which is converted into electrical energy when needed.
- Starter Motor: The starter motor is an electric motor that converts electrical energy from the battery into mechanical energy. It cranks the engine to initiate the combustion process.
- Solenoid: The solenoid is a switch that controls the flow of electrical current from the battery to the starter motor. When the ignition key is turned, the solenoid engages the starter motor.
- Ignition Switch: The ignition switch is used to start and stop the engine. It sends electrical signals to the starter motor and solenoid to initiate the cranking process.
- Wiring: The wiring connects all the components together, allowing the electrical current to flow in the cranking circuit.
These components work together to provide the necessary electrical power and mechanical force to crank the engine and start the vehicle.
