RLC Circuits and Resonance

Q1:

What is the total current?

A 15.6 mA

B 17.8 mA

C 21.9 mA

D 26.0 mA

ANS:A - 15.6 mA

There is another way to do it.

Xt = Xl-Xc.
Xl = 2*3.14*L*f = 28.26.
Xc = 1/(2*3.14*C*f) = 10.06.

Xt = Xl-Xc = 18.20.

Z = sqrt(Xt^2+Xl^2) = APPROX 21.

I = V/Z = 317/21 = 15.6.
