What are $LC$ oscillations?

  • A
    $A$ process where energy oscillates between a capacitor and an inductor.
  • B
    $A$ process where energy is dissipated as heat in a resistor.
  • C
    $A$ process where current remains constant in a circuit.
  • D
    $A$ process where voltage remains constant in a circuit.
