उत्तर
- Heavy rain and thundering are accompanied by lightning. Lightning is basically the discharge of huge amounts of electric charge from clouds towards the ground.
- These charges may pass through the metallic rod of the umbrella to the person carrying it. Hence, the person might get severe electric shock and die.
- Thus, it is not advisable and safe to go out with an umbrella when there is heavy rain, lightning or thunder.
