Problem

A sinusoidal voltage of peak value 283 V and angular frequency 320/s is applied to a series LCR circuit. Given that

R = 5 \Omega

L = 25

mH and

C = 1000 \mu F

. The total impedance, and phase difference between the voltage across the source and the current will respectively be : (1)

10 \Omega

and

\tan^{-1} \left( \frac{5}{3} \right)

(2)

7 \Omega

and

45^\circ

(3)

10 \Omega

and

\tan^{-1} \left( \frac{8}{3} \right)

(4)

7 \Omega

and

\tan^{-1} \left( \frac{5}{3} \right)
