Since the voltage source is parllel to both resistances.

You can't just simply calculate Req like 2 resistors in parallel, proper impedance have to be calculated for parallel RL circuit.
I = V/Z.
Z= 1/*(1/R)^2+(1/XL)^2.
I = V/Z.
Z= 1/*(1/R)^2+(1/XL)^2.

I = V/R.
I = 12/125 = 0.12,
0.12 * 10^2,
0.12 * 1000 = 120mA.
I = 12/125 = 0.12,
0.12 * 10^2,
0.12 * 1000 = 120mA.
