Question

(a) why do electricians wear rubber hand gloves while working with electricty?
(b) what p.d. is needed to send a current of 6 A through an electrical appliance having a resistance of $40\Omega$ ?

Answer 1

a)
Rubber is an insulator and does not allow the passage of electric current through it, so when electricians wear rubber gloves electric current cannot pass through them, so they don't get an electric shock. Human beings are conductors of electricity, and one can experience a shock when working with electricity.

b)
