MCQ
Ohm's law is _________ .
- A$V = IR$
- B$I=\frac{V}{R}$
- C$R =\frac{ V }{ I }$
- ✓All of these
✓
Answer
Correct option: D.
All of these
(d)
All of these
Explanation :
Ohm's law states that the potential difference is proportional to current flowing in that circuit.
Hence $V \propto I$
$
V=RI
$
Where, $R$ is resistance.
It can be written as
$
R=\frac{V}{I}
$
or $I=\frac{V}{R}$
