calculate the inductive reactance and r.m.s surrent in the circuit if the frequency is 60Hz.?

In a purely inductive AC circuit, L= 250mH and the r.m.s voltage is 150V.

ii) if the frequancy is increased to 6kHz, calculate the new r.m.s. current in the circuit.

In an inductor, V/I = L*omega (ref.), I = V/(L*omega). At 60 Hz omega = 2pi*60.
There you are.
