This tool is used for calculations involving the discharge of a capacitor through a fixed-value resistor. Given a capacitance value as well as beginning and end voltages, this calculator solves for either time or resistance, calculating the resulting initial power dissipation in the resistance and the total energy discharged to zero volts.
Discharge/Pre-charge resistors Calculator used to calculate the voltage that a capacitor with a a capacitance and a resistor in series with it, will discharge to after time has elapsed. You can use this calculator to calculate the voltage that the capacitor will have discharged after a time period has elapsed.
To discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. In regard to the "health" of the capacitor, high discharge currents can damage it or reduce its lifespan, so it is favorable to discharge through a resistor. How do you calculate the initial discharge of a capacitor?
The greater the amount of time has elapsed, the more the capacitor will discharge. The less time that has elapsed, the less time the capacitor has to discharge. Thus, the larger the t value, the smaller V C. The The greater the resistance, R, of the resistor, the slower the discharge process will be.
After 5 time periods, a capacitor discharges up to near 0% of all the voltage that it once had. Therefore, it is safe to say that the time it takes for a capacitor to discharge is 5 time constants. Capacitor Safety Discharge Calculator - This calculator is used to calculate the discharge of a capacitor through a fixed-value resistor.
Capacitance - The capacitor's capacitance. The resistor's resistance is called resistance. Time - The amount of time it takes to charge or discharge a device. Time, t, the resistance of the resistor, R, and the capacitance of the capacitor, C, are the three variables that influence how the initial voltage discharges.
