MCQ
Find out the $e.m.f$. produced when the current changes from $0$ to $1 \,A$ in $10 \,second$, given $L = 10$ $\mu H$
- A$1\, V$
- ✓$1$ $\mu V$
- C$1\, mV$
- D$0.1\,V$
✓
Answer
Correct option: B.
$1$ $\mu V$
b
(b) $|e|\, = L\frac{{di}}{{dt}}$
(b) $|e|\, = L\frac{{di}}{{dt}}$
$\Rightarrow \,|e|\, = 10 \times {10^{ - 6}} \times \frac{1}{{10}} = 1\,\mu V$
