Question

The relationship between the potential difference and the current in a conductor is stated in the form of a law.
$\left(i\right)$ Name the law.
$\left(ii\right)$ What does the slope of V-I graph for a conductor represent?
$\left(iii\right)$ Name the material used for making the connecting wire.

Answer 1

$\left(i\right)$ The relationship between the potential difference and the current in a conductor is known as Ohm's law. It is given by $V=IR$
$\left(ii\right)$ The slope of the V-I graph for a conductor represents the resistance of the conductor.
$\left(iii\right)$ The material used for making the connecting wire is Copper since it has less resistance.
