Electricians wear rubber handgloves while working with electrical devices. Give reasons.

Solution

Rubber is an insulator.
An insulator is a material with infinitely high resistivity and therefore it does not allow electrical current to pass through it.
The resistivity range of insulators is from $10^{12} Ω m$ to $10^{17} Ω m$ .
Thus, wearing electrical gloves protects an electrician from electrical shocks.
