Enter the total capacitance (F), the change in voltage (volts), and the change in time (volts) into the calculator to determine the Capacitor Current.

## Capacitor Current Formula

The following formula is used to calculate the Capacitor Current.

Icap = C * dV / dT
• Where Icap is the Capacitor Current (amps)
• C is the total capacitance (F)
• dV is the change in voltage (volts)
• dT is the change in time (volts)

To calculate capacitive current, multiply the total capacitance by the change in voltage divided by the change in time.

## How to Calculate Capacitor Current?

The following example problems outline how to calculate Capacitor Current.

Example Problem #1

1. First, determine the total capacitance (F). In this example, the total capacitance (F) is determined to be 200 .
2. Next, determine the change in voltage (volts). For this problem, the change in voltage (volts) is measured to be 5 .
3. Next, determine the change in time (volts). In this case, the change in time (volts) is found to be 6.
4. Finally, calculate the Capacitor Current using the formula above:

Icap = C * dV / dT

Inserting the values from above and solving yields:

Icap = 200* 5 / 6 = 166.66 (amps)

Example Problem #2

Using the same method as above, determine the variables required by the formula. For this example problem, these are:

total capacitance (F) = 700

change in voltage (volts) = 10

change in time (volts) = 5

Enter these given values into the calculator or above yields:

Icap = 700 * 10 / 5 = 3500 (amps)
