Question
What can be added to make the electrons flow in this electric circuit?
- Seawater
- Rubber
- Wood
- Glass
Hint:
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.
