Question

What can be added to make the electrons flow in this electric circuit?

  1. Seawater
  2. Rubber
  3. Wood
  4. Glass

hintHint:

The current flows continuously when there is a conductor connected between the battery and the switch.

The correct answer is: Seawater


    Sea water can be added to make the electrons flow in this electric circuit.
    • An electric circuit is incomplete without a conductor.
    • It is the pathway used to enable the flow of current from the generator.
    • The sea water acts as an electric conductor that can be added (at A) between the battery and the switch to make the current flow.
