Homework Statement
Information given:
Resistance=105 ohms, , XL= 212 ohms, XC= 93 ohms
V rms is 143 Volts.
Frequency of the circuit is f. Not defined.
Information Solved for:
Impedance (Z) = 158.7
I rms=.901 Amps
Phase angle = 48.58
The final question, which I cannot solve for some reason, is this:
At the instant the voltage across the generator is maximum, what is the current I?
I know that the current will be less than maximum as it lags in this case, but I don't know by what factor or how to compute it from here. Any suggestions?
Homework Equations
tan(theta)=(XL-XC)/R
Vmax=ImaxZ=2^1/2*V rms
Z= (XL - XC) / R
The Attempt at a Solution
I have tried everything here and it's been pathetic so. I tried using the angle difference from 45 degrees (3.58) as somehow why I will not be maximized as the current is out of phase with V. This was wrong. Any suggestions?
