How do you calculate capacitor current?

The formula which calculates the capacitor current is I= Cdv/dt, where I is the current flowing across the capacitor, C is the capacitance of the capacitor, and dv/dt is the derivative of the voltage across the capacitor. You can see according to this formula that the current is directly proportional to the derivative of the voltage.

What is a capacitor charge current calculator?

» Electrical » Capacitor Charge Current Calculator The Capacitor Charge Current Calculator is an essential tool for engineers, technicians, and students who work with capacitors in electrical circuits. This calculator determines the charging current required to change the voltage across a capacitor over a specific period.

What is the current going through a capacitor?

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.

How much voltage does a capacitor have?

The voltage at which the capacitors are applied can vary +5% or even up to +10%. Voltage less than nominal is not a concern for as the lower voltage will result in lower capacitor current. Harmonics can create additional current flow in the capacitors any where from +20% to +35% of the rated current.

How to calculate capacitor reactance?

Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance. Capacitive reactance is calculated using: Where Q factor or Quality factor is the efficiency of the capacitor in terms of energy losses & it is given by: QF = XC/ESR Where
