Question

Statement 1: In a purely resistive element of a series LCR AC circuit, the maximum value of r.m.s. current increases with increase in the angular frequency of the applied e.m.f.

Statement 2: For an RLC circuit,

Imax=εmaxZ,Z=R2+ωL1ωC2,

where Imax is the peak current in a cycle.

Easy
Solution

The maximum value of r.m.s. current =εrmsR. It does not depend upon ω.
