This Capacitor Current Calculator calculates the current which flows through a capacitor based on the capacitance, C, and the voltage, V, that builds up on the capacitor plates.
To calculate the current (I) charging a capacitor, you can use the following formula: I = C * (dV/dt) where: This formula highlights that the charging current is directly proportional to both the capacitance of the capacitor and the rate of change of voltage over time.
The capacitive current can be calculated using the formula: \ [ I_ {cap} = C \cdot \frac {dV} {dT} \] where: \ (dT\) is the change in time in seconds. For instance, if a capacitor with a total capacitance of 2 F experiences a voltage change of 5 volts over a period of 1 second, the capacitor current would be:
The product of the two yields the current going through the capacitor. If the voltage of a capacitor is 3sin (1000t) volts and its capacitance is 20μF, then what is the current going through the capacitor? To calculate the current through a capacitor with our online calculator, see our Capacitor Current Calculator.
As the voltage being built up across the capacitor decreases, the current decreases. In the 3rd equation on the table, we calculate the capacitance of a capacitor, according to the simple formula, C= Q/V, where C is the capacitance of the capacitor, Q is the charge across the capacitor, and V is the voltage across the capacitor.
Click the “Calculate” button, and the calculator will instantly display the capacitor current (Icap) in amperes (A). The calculator simplifies a potentially complex calculation, saving you time and effort. The formula used by our Capacitive Current Calculator is as follows: Icap = C * (∆V / ∆T) Where: Icap is the capacitor current in amperes (A).
