In parallel RL circuit, try to solve first the value of admittance (Y) =sqrt ( (1/R) ^2+ (1/XL) ^2) ; XL=2*pi*f*L, meaning, when f (frequency) decreased. Your Y increased. And remember that impedance (Z) is inversely proportional to Y. Z=1/Y.

Impedence of parallel circuit is Xl = 2piefl.
directly porpotainal to Frequency.
As frequency decreses impedence decerases

XC is capacitive reactance. XL is inductive reactance.
Parallel RL circuit has inductive reactance not capacitive.

As impidence(X) directly propotional to the frequency,
so, with decreses of frequency , impidence decreses
so, with decreses of frequency , impidence decreses

R in parallel with XL so total value of Z but frequency only depend on XL that is decreases.

Solve it by using parallel combination of r and xl you will get answer, which is decrease.

Why we take XL and not XC please explain me?
