Understanding Electrical Continuity Testing

What is the primary purpose of an electrical continuity test?

• To determine the power consumption of a device.

• To test the insulation resistance of wires.

• To verify the integrity of electrical connections and ensure current can flow.

• To measure the voltage across a circuit.

Which instrument is commonly used to perform a continuity test?

• Multimeter

• Frequency counter

• Signal generator

• Oscilloscope

What does a reading of zero ohms indicate during a continuity test?

• There is a complete electrical connection.

• The resistance is infinite.

• The circuit is open and incomplete.

• There is no electrical connection.

Why is it important to ensure electrical continuity in circuits?

• It is important to ensure electrical continuity in circuits to allow uninterrupted current flow, ensuring proper device operation and safety.

• To create a short circuit for testing purposes

• To reduce the current flow for safety

• To increase resistance in the circuit

What safety precautions should be taken before performing a continuity test?

• Ensure the circuit is powered on during the test.

• Ensure the circuit is powered off and disconnected from any power source.

• Connect the circuit to a power source before testing.

• Use a multimeter without checking the settings first.
