Home » Electrical Circuits » Capacitors in AC Circuits When a capacitor is subject to a voltage across its terminals, it starts charging until its charge becomes at the level of the applied voltage. During the time that charging takes place a current flows in the circuit (wires connecting the capacitor to the power source).
Capacitors in AC circuits are key components that contribute to the behavior of electrical systems. They exhibit capacitive reactance, which influences the opposition to current flow in the circuit. Understanding how capacitors behave in series and parallel connections is crucial for analyzing the circuit's impedance and current characteristics.
Capacitors store energy on their conductive plates in the form of an electrical charge. The amount of charge, (Q) stored in a capacitor is linearly proportional to the voltage across the plates. Thus AC capacitance is a measure of the capacity a capacitor has for storing electric charge when connected to a sinusoidal AC supply.
As the capacitor charges fully to the maximum value of the voltage, the charging current drops towards zero. When the voltage begins to drop, capacitor starts charging. So the relation between the voltage and current is described as 90 degrees out of phase. Therefore, the capacitor current leads the applied voltage by an angle 90 degrees.
Charging is when the voltage across the plates builds up quickly to equal the voltage source. Once a capacitor reaches its fully charged state, the current flow stops. Once a charged capacitor is disconnected from a circuit it will remain charged. To discharge a capacitor, it will need to be placed in a closed circuit without a voltage source.
