20.5: RC Circuits

Charging an RC Circuit: (a) An RC circuit with an initially uncharged capacitor. Current flows in the direction shown as soon as the switch is closed. Mutual repulsion of like charges in the capacitor progressively slows the flow as the capacitor is charged, stopping the current when the capacitor is fully charged and Q=C⋅emf.

How are current and voltage out of phase in capacitive circuit?

The formula for current through a capacitor is: I = C * (dV / dt) The small d stands for a tiny change, known as delta(δ) This means the faster the voltage change, the higher the current through the capacitor. The capacitor acts as a differentiator.

8.4: Transient Response of RC Circuits

This creates the initial current, and this current starts to charge the capacitor (the initial rate being equal to (i/C) as dictated by Equation 8.2.6). According to Kirchhoff''s voltage law, as the capacitor voltage begins to increase, the resistor voltage must decrease because the sum of the two must equal the fixed source voltage.

How Capacitors Work

The Current Through a Capacitor. When you start charging a capacitor, the current flows freely without any resistance in the very beginning. As the capacitor charges, the resistance increases so that less and less current can flow. When the capacitor is fully charged no more current flows through it:
