Question

1. What is electric current?
2. How is electronic current different from conventional current?
3. Differentiate between conductors and insulators.
4. What is an electrolyte?
5. Why is zinc electroplated on iron?
6. What is electric current?​

Answer 1

1 The rate of the flow of charge is called an electric current. I = Q/t

2 The flow of electronic current is from negative to positive whereas the flow of conventional current is from positive to negative.

3 Substances which allow electric charges to flow through them are called conductors of electricity. Examples: Metals like iron, copper, aluminium, etc. Substances that do not allow electric charges to flow through them are called non-conductors or insulators of electricity. Examples: Plastic

4: A substance which conducts electricity in the liquid state or when dissolved in water and breaks up chemically during the process is called an electrolyte.

5 Zinc is electroplated on iron to prevent it from rusting
