Question

The instrument that is used to check whether a particular material allows current to pass through is called

  1. Marker
  2. Switch
  3. Bulb
  4. Tester

hintHint:

A tester helps to detect the current flow in a circuit.

The correct answer is: Tester


    • The current flow in a circuit, when it is properly connected to all the required components.
    • The battery supplies the current and the conductor helps the current pass through the circuit.
    • The instrument that is used to measure the electrical flow is called a tester.
