Driven RLC Circuit Using Phasors


This simulation shows the phasor representation of a series RLC circuit. Adjust the values of R, L, and C using the sliders. Change how the circuit is driven by adjusting the emf amplitude and driving frequency. Use the check boxes to select which graphs are shown.
  1. Can you put the circuit in resonance? Can you calculate the resonant frequency?
  2. When is the circuit inductive? When is it capacitive?
  3. Can any of the voltages ever be larger than the emf amplitude?
  4. What effects does changing R have?
  5. Current is not shown, but can you tell when it has the largest amplitude?
