• To display the fuel system components of a vehicle.

What is the function of a fuse in an automotive electrical system?

• To improve the fuel efficiency of the vehicle

• To reduce the voltage in the electrical system

• To protect the electrical components from damage due to excessive current flow.

• To increase the current flow in the electrical system

What are the common signs of a faulty automotive electrical component?

• Loud engine noise

• Strong brakes

• Dim or flickering lights, difficulty starting the vehicle

• Smooth acceleration

How can you test the continuity of an automotive electrical circuit?

• Listen for a buzzing sound to indicate continuity

• Look for sparks when connecting the circuit

• Use a multimeter to check for a complete path for the flow of electricity.

• Use a compass to check for the flow of electricity

What are the safety precautions to be taken when working with automotive electrical systems?

• Use metal tools without insulation

• Wear sandals and shorts while working

• Keep the battery connected at all times

• Use insulated tools, wear protective gear, disconnect the battery, and follow proper procedures for handling electrical components.

Explain the concept of voltage drop in automotive electrical circuits.

• Voltage drop occurs when there is an increase in voltage as the current flows through the circuit

• Voltage drop is not affected by resistance in the circuit

• Voltage drop only happens in non-automotive electrical circuits

• Voltage drop in automotive electrical circuits occurs when there is a decrease in voltage as the current flows through the circuit due to resistance.
