When a particular inductor is connected to a source of sinusoidally varying emf with constant amplitude and a frequency of 60.0 Hz, the rms current is 3.00 A. What is the rms current if the source frequency is doubled?
  1.12.0 A
  2.6.00 A
  3.4.24 A
  4.3.00 A
  5.1.50 A

Question 2

A series RLC circuit contains a 20.0-V resistor, a 0.750-mF capacitor, and a 120-mH inductor. If a sinusoidally varying rms voltage of 120 V is applied across this combination of elements, what is the rms current in the circuit when operating at its resonance frequency?
  1.2.33 A
  2.6.00 A
  3.10.0 A
  4.17.0 A
  5.none of those answers
