DC circuitsQuestion 848 of 1506

The voltage applied to a capacitor is rising. How does the capacitor act in the circuit?

  1. As a source, supplying current
  2. As an open switch that blocks all energy
  3. As a coil that stores energy in a magnetic field
  4. As a load that takes current
Show answer

Correct answer: As a load that takes current

When voltage rises, the stored energy rises, so the capacitor draws current from the circuit.
