Circuit: current value in generator

[saritche]

Homework Statement

AC voltage source rms voltage of 158. Circuit has Resistance 106 X(L) is 205 and X(C) is 110
At the instant the voltage across the generator is at its maximum value, what is the magnitude of the current in teh circuit?

Homework Equations

V=IR, Vmax=ImaxZ
I found Z, Irms

The Attempt at a Solution

voltage across generator is not in phase with the current so it will be less than the max value but I don't know by what factor it will be less

The load can be inductive or capacitive to make phase angle = 0. So the minimum |Z| = R.

I would suggest using the equations V=IR and Vmax=ImaxZ to solve for the current in the circuit. Since the voltage across the generator is at its maximum value, we can use Vmax=ImaxZ to find the maximum current in the circuit. Using the given values of resistance, inductive reactance, and capacitive reactance, we can calculate the impedance (Z) of the circuit. From there, we can solve for Imax by rearranging the equation to Imax=Vmax/Z. This will give us the maximum current in the circuit at the instant the voltage across the generator is at its maximum value.
