To calculate the current through a capacitor with our online calculator, see our Capacitor Current Calculator.

What is the relationship between voltage and current in a capacitor?

Voltage and Current Relationship in Capacitors In a capacitor, current flows based on the rate of change in voltage. When voltage changes across the capacitor’s plates, current flows to either charge or discharge the capacitor. Current through a capacitor increases as the voltage changes more rapidly and decreases when voltage stabilizes.

What is capacitor charge current?

The ability of a capacitor to store charge, measured in farads. The difference in voltage across the capacitor before and after charging. The duration over which the voltage change occurs, measured in seconds. To illustrate the use of the Capacitor Charge Current Calculator, let’s consider a practical scenario.

What happens when a capacitor is charged?

When a capacitor charges, current flows into the plates, increasing the voltage across them. Initially, the current is highest because the capacitor starts with no charge. As the voltage rises, the current gradually decreases, and the capacitor approaches its full charge.

How does a capacitor work?

Capacitors store and release energy, but the way current flows through them is unique. Unlike resistors, capacitors do not allow a steady flow of current. Instead, the current changes depending on the capacitor’s charge and the frequency of the applied voltage.
