Question

A current of 11 A flows through a coil, when con-
nected to a 110 V d.c. source. When 110 V a.c.
of 50 Hz is applied to the coil, only 0.5 A current
flows. Calculate the impedance

I know the solution but I don't know whether RMS voltage is given for peak voltage is given

help me plz.. how to identify in ques like this one​
