Capacitive Current Calculator

Formula

The formula to calculate the Capacitor Current (I_cap) is:

\[ I_{cap} = C \times \frac{dV}{dT} \]

Where:

\( I_{cap} \) is the Capacitor Current (A)
\( C \) is the Total Capacitance (F)
\( dV \) is the Change in Voltage (V)
\( dT \) is the Change in Time (s)

What is Capacitor Current?

Capacitor current refers to the current that flows through a capacitor as it charges or discharges. This current is directly proportional to the rate of change of voltage across the capacitor and the capacitance value. Understanding capacitor current is crucial in designing and analyzing circuits that involve capacitors.

Example Calculation

Let's assume the following values:

Total Capacitance (C) = 10 F
Change in Voltage (dV) = 5 V
Change in Time (dT) = 2 s

Using the formula to calculate the Capacitor Current:

\[ I_{cap} = 10 \times \frac{5}{2} = 10 \times 2.5 = 25 \text{ A} \]

The Capacitor Current is 25 A.
