The resistance of a piece of rubber is higher than that of a piece of copper of the same dimensions.

State the formula correlating the electric current flowing in a conductor and the voltage applied across it. Also, show this relationship by drawing a graph. What would be the resistance of a conductor, if the current flowing through it is $0.35 \ A$ when the potential difference across it is $1.4 \ V$?

$n$ equal resistors are first connected in series and then connected in parallel. The ratio of the maximum to the minimum resistance is

Distilled water acts as ........ for electricity.

$A$ series circuit has only one conducting path for the electrons that move through it; a parallel circuit has multiple conducting paths.

Give an example of a metal which is the best conductor of heat.
