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
- First, determine the total capacitance (F). In this example, the total capacitance (F) is determined to be 200 .
- Next, determine the change in voltage (volts). For this problem, the change in voltage (volts) is measured to be 5 .
- Next, determine the change in time (volts). In this case, the change in time (volts) is found to be 6.
- 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)
