Questions & Step-by-Step Solutions

In an RC circuit, if the capacitor is fully charged, what is the current through the circuit?
  • Step 1: Understand what an RC circuit is. An RC circuit consists of a resistor (R) and a capacitor (C) connected together.
  • Step 2: Know what it means for a capacitor to be fully charged. A fully charged capacitor has stored all the energy it can from the power source.
  • Step 3: Realize that when a capacitor is fully charged, it acts like a barrier to current. This means no more current can flow through the circuit.
  • Step 4: Conclude that since the capacitor blocks current flow when fully charged, the current through the circuit is zero.
