This is the capacitor energy calculator, a simple tool that helps you evaluate the amount of energy stored in a capacitor. You can also find how much charge has accumulated in the plates. Read on to learn what kind of energy is stored in a capacitor and what is the equation of capacitor energy.
A capacitor in an AC circuit has a power (Pc) of 180 volt-amperes reactive (VAR) and a voltage (Vc) of 90 volts (V) across it. Calculate the current through the capacitor. Given: V c (V) = 90V, P c (W) = 180W. Capacitor power, P c (W) = I c (A) * V c (V)
Finally, you can find the energy by calculating (½) C [vC (t)] 2. When you do this, you get the bottom-right graph shown here. Here, the capacitor’s energy increases when it’s absorbing power and decreases when it’s delivering power. John M. Santiago Jr., PhD, served in the United States Air Force (USAF) for 26 years.
Capacitor power, P c (W) in watts is calculated by the product of current running through the capacitor, I c (A) in amperes and voltage running through the capacitor, V c (V) in volts. Capacitor power, P c (W) = I c (A) * V c (V) P c (W) = capacitor power in watts, W. V c (V) = voltage in volts, V. I c (A) = current in amperes, A.
The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V
The Average power of the capacitor is given by: Pav = CV2 / 2t where t is the time in seconds. When a capacitor is being charged through a resistor R, it takes upto 5 time constant or 5T to reach upto its full charge. The voltage at any specific time can by found using these charging and discharging formulas below:
