Answer 1

A) it is not safe for the electrician to carry out electric repairs outdoors during rains

It is not safe to repair electrical appliances outdoors during heavy downpour. This is because rain water contains dissolved salts. Therefore, rain water can conduct electricity. The electrician may get electrical shocks while working outdoors during rain.

B) Ram staying in Chennai tested drinking water and sea water with his tester . He found that the compus needle deflects more in case of sea water. Why ?

Sea water contains more amount of salt than drinking water. So the sea water is a better conductor of electricity. This is the reason that the compass needle deflects more in case of sea water.
