As we know that XL=ω L=2 π V L=(E0/I0) XL=(√2 Em s/I0) =(1.414 × 200/2 × (22)7 × 1 × 0.9) v=50 Hz

Q. What should be the frequency of alternating $200 V$ supply so as to pass a maximum current of $0.9 A$ through an inductance of 1 henry?

$40 Hz$

$50 Hz$

$60 Hz$

$70 Hz$

As we know that
$X_{L} = ω L = 2 πV L = \frac{E _{0}}{I _{0}}$
$X_{L} = \frac{2 E _{m s}}{I _{0}}$
$= \frac{1.414 \times 200}{2 \times \frac{22}{7} \times 1 \times 0.9}$
$v = 50 Hz$
