The inverse of resistance is called ________.

Resistance:

1. Resistance $\left(R\right)$ can be defined as the measure of opposition to the flow of current through a circuit.
2. According to Ohm's law, “The current $\left(I\right)$ flowing in a circuit is directly proportional to the potential $\left(V\right)$ across it, given all physical conditions and temperature remains same.”
3. So, $V\propto I$. Thus a proportionality constant, which is resistance, is introduced $V=IR$.
4. Thus, the formula for resistance can also be given as $R=\frac{V}{I}$.
5. $R$ is constant for a given metallic wire, if the temperature remains constant.
6. Its SI unit is ohms $\left(\Omega \right)$.

Conductance:

1. Conductance $\left(C\right)$ can be defined as the measure of the ease with which the current flows through a circuit.
2. Conductance is the reciprocal of resistance, $C=\frac{1}{R}$.
3. Its SI unit is seimens $\left(S\right)$, also known as mho.

Hence, the inverse of resistance is called conductance.
