If the current through an inductor increases from 2 A to 3 A, the magnetic energy stored in the inductor increases by
- A \(125 \%\)
- B \(225 \%\)
- C \(50 \%\)
- D \(75 \%\)
Answer & Solution
Correct Answer
(A) \(125 \%\)
Step-by-step Solution
Detailed explanation
Magnetic energy stored in the inductor is \(\mathrm{U}=\frac{1}{2} \mathrm{LI}^2 \Rightarrow \mathrm{U} \propto \mathrm{I}^2\)…
