Question

The formula (or mathematical expression) that represents Ohm's law is:-

• A. V=IR
• B. $\frac{V}{I}=R$
• C. Both a and b
• D. Neither a nor b

Answer 1

The correct option is C

Both a and b

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

i.e., $V\propto I$

or V= IR [R is the constant of proprionality]

$\Rightarrow \frac{V}{I}=R\text{or}\frac{V}{R}=I$
