Question

Explain why it is safer to use a wireless telephone instead of a landline telephone during lightning.

Answer 1

Explain using conduction through a person:

1. Lightning is just a phenomenon of electrical discharge.
2. During lightning, the electric charge of the atmosphere might discharge through the telephone landline wires.
3. This might electrocute a person when he uses the landline telephone as the human body is a good conductor of electricity.
4. This is what makes the wireless telephone safer than the landline telephone during lightning.
