Answer / suvodeep
relation between current and frequency will depend on the
nature of the circuit.However I feel the relation between
current and frequency will like I (current) is propotional to
frequency.
the below example can be taken as a refrence:
for a purely capacitive circuit we know, V/I=1/wC, where
V=Voltage, I = Current, w=Angular Frequency, C=Capacitance
we also know dat w=2(pi)xf
then the relation will come like I=2(pi)xfxCxV Hence its
proved dat I is Proportional to f.

In a Inductive CKT:-On reducing the frequency the inductive reactance is also reduce n in this the total current in that ckt is increase.
in a capacitve ckt:-if the frequency is reduced, the condensr will draw less current 4m the same supply.
