Question 199: AC fundamentals

Question

What happens to the inductive reactance and the current in a purely inductive circuit if the frequency is halved?

Accepted Answer

$${X_L} = \omega L$$
$$X{'_L} = \left( {{{{X_L}} \over 2}} \right)$$
$$ \because $$ $$I = {V \over {{X_L}}}$$
& $$I' = {{2V} \over {{X_L}}} = 2I$$

Answer

Both, inducting reactance and current will be doubled.

Answer

Inductive reactance will be doubled and current will be halved.
