Q1:

An RLC series circuit is excited by an ac voltage v = 1 sint. If L = 10 H, C = 0.1 F peak value of voltage across R is

A 0.707 V

B 1 V

C 1.44 V

D indeterminate as value of R is not given

ANS:B - 1 V

It is a series resonant circuit and peak voltage across R is equal to peak value of source voltage.
