What is the resulting current in a series circuit with a resistor and capacitor?

[patep023]

I have solved it (:

Homework Statement

Ir=Impedance of a resistor = 330
Ic=Impedance of a capacitor=318
V= Sinusoidal Voltage = 240 V (RMS) is applied across the series combination.
calculate the resulting current.

Homework Equations

Not sure

The Attempt at a Solution

I am really not sure how I would work out the resulting current.
Answer
I = 250/sqrt(330^2+318^2)

I have solved it (:

Well done.
Please help others by explaining how you got the answer.

 

[rude man]

Should be 240/sqrt(330^2 + 318^2).
Also, you have determined the magnitude of the current but not its phase.

 

[patep023]

yes, sorry it's supposed to be 240 not 250. I am not sure what its phase is

 

[rude man]

I am not sure what its phase is

Gonna take a shot at it?
