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 sinat, where εm=120 V and ω=833 radians/second. The values for the remaining circuit components are: R=90Ω,L=41.4mH, and C=14μF. 1) What is Z, the impedance of the circuit? Ω You currentiy have 0 submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question. 2) What is I max, the magnitude of the maximum value of the current in the circuit? A You currentiy have 0 submissions for this question. Only 10 submission are alfowed. You can make 10 more submissions for this question. 3) What is φ, the phase angle between the generator voltage and the current in this circuit. The phase φ is defined to be positive if the current leads the generator voltage, and negative otherwise. degrees You currently have 0 submissions for this question. Only 10 submission are allowed.

The voltage across the generator is zero when the magnitudes of the voltages across the inductor and the capacitor are maximum. The current in the circuit is zero when the magnitudes of the voltages across the inductor and the capacitor are maximum. The magnitude of the voltage across the generator is maximum when the magnitudes of the voltages across the inductor and the capacitor are maximum. The magnitude of the current in the circuit is maximum when the magnitudes of the voltages across the inductor and the capacitor are maximum. There is no time when the magnitudes of the voltages across the inductor and capacitor are maximum. You currently have 0 submissions for this question. Only 10 submission are allowed.
