What is the frequency of direct current?

What is the frequency of direct current?

What Is the frequency of alternating current (A.C.) ?

Current through an AC series L-C-R circuit is 2 A if operated at resonance frequency , and 1 A if operated at 50% less than resonant frequency . The current (in A) if the frequency is 100% more than the resonant frequency , is A. sqrt 2 B.1 C. sqrt 3 D.Data insufficient
