1. The problem statement, all variables and given/known data 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? 2. Relevant equations tan(theta)=(XL-XC)/R Vmax=ImaxZ=2^1/2*V rms Z= (XL - XC) / R 3. 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?
