Differentiate between conductors and non-conductors of electricity.
Important Questions on Electricity and Circuits
We can easily draw electrical circuits by following some simple rules.
1. Use a ruler to draw straight lines to represent the wires.
2. Use the correct circuit symbols to represent different components.
3. Ensure that the circuit is closed and has no gaps.
