A circuit is constructed with an AC generator, a resistor, capacitor and inductor as shown. The generator voltage varies in time as ε=Va=Vb= εm sinit, where εm=120 V and ω=700 radians/second. The values for the remaining circuit components are: R=132Ω,C=533μF. The value for L is unkown. What is known is that the voltage across the generator leads the current in the circuit by φ=64 degrees. 1) What is t1, the first time after t=0 when the magnitude of the voltage across the inductor is maximum? seconds You currently have 0 submissions for this question.

The value of C would need to be decreased The value of C would need to be increased. It is impossible to bring the voltage across the generator in phase with the current in the circuit by only changing the value of C, keeping all other circuit parameters fixed.
