Question

1) What is the power outlet for an rms voltage of a standard 220 V?

2) Consider a driven RLC series AC circuit. At frequency f1 the capacitive reactance is twice the inductive reactance. Determine frequency f2 as a function of f1 so that the inductive reactance is twice the capacitive reactance.

3) A standard 120V ac source, connecting wires, and two ideal identical transformers are available. Each transformer has a different number of turns in the two coils. How many different voltages can be supplied to a circuit using these resources? (Consider that the ideal transformers can be flipped in the circuit so that
Nprimary can be larger or smaller than Nsecondary).
  
4) Consider a RLC series circuit connected to a 320 V rms voltage source with a frequency of 220 Hz. What is the peak current through the circuit if R = 230 Ω, C = 80 μF, and L = 3.5 mH?

5) An 6.0 mH inductor is connected to an AC source. Determine the frequency of the AC source when the inductive reactance is 20 Ω.
