## Homework Statement

For the series RLC circuit shown in Fig. Q8, determine the voltage across each element, and draw a complete phasor diagram.

## Homework Equations

## The Attempt at a Solution

Total Impedance:

Z = R+Xc+Xl

= 75 - 60j + 25j

= 75-j35

Z = 82.76∠-25.02 (Phasor form)

Total Current:

I = V/Z

= (10∠0)/(82.76∠-25.02)

= 0.12∠25.02

Now my question is when finding the voltage across the resistor will it just be the magnitude of the current*resistance ie, 0.12*75 ?

Also when finding the voltage across the inductor, is this correct ?

V = (0.12∠25.02)*(75.06∠18.43)......Z = 75+j25, in phasor form = 75.06∠18.43

= 9∠43.45

And the capacitor

V = (0.12∠25.02)*(96.05∠-38.66)......Z = 75-j60, in phasor form = 96.05∠-38.66

= 11.53∠-13.64

Thanks
