Question

Which of the following depicts the mathematical form of Ohm’s Law?

• A. $I=\left(1/R\right)\times V$
• B. $V=\frac{I}{R}$
• C. $I=\frac{R}{V}$
• D. $R=\frac{I}{V}$

Answer 1

The correct option is A $I=\left(1/R\right)\times V$

Ohm’s Law states that potential difference, $V$ is proportional to the current, $I$ and the constant of proportionality is the resistance, $R$.

i.e., $V=I\times R$

Hence, $I=\frac{V}{R}$
