A resistor, an inductor and a copacitor are all connected in series to an AC generator with a lequency of 60 Hz and Vmer = 20 volts If the value of the resistor is of 5 ohms, the inductor is of 2.5 mH and the capacitor of 50 4C • Compute the impedance of the circuit • What is the value of the Iraus and Irns? • What is the average power released by the circuit?

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 = εmsinωt, where εm = 120 V and ω = 276 radians/second. The inductance L = 170 mH. The values for the capacitance C and the resistance R are unkown. What is known is that the current in the circuit leads the voltage across the generator by φ = 52 degrees and the average power delivered to the circuit by the generator is Pavg = 126 W. 1) What is Imax, the amplitude of the current oscillations in the circuit? 2) What is R, the value of the resistance of the circuit? 3) What is C, the value of the capacitance of the circuit? 4) The value of ω is now changed, keeping all other circuit parameters constant, until resonance is reached. How was ω changed? ω was decreased ω was increased 5) What is the average power delivered to the circuit when it is in resonance?
