Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.
Using a discharge tool with a resistor can control the discharge rate. Initial Voltage: The higher the initial voltage across the capacitor, the longer it will take to discharge. Capacitors with higher voltages will take more time to release their stored energy compared to those with lower voltages.
After 2 time constants, the capacitor discharges 86.3% of the supply voltage. After 3 time constants, the capacitor discharges 94.93% of the supply voltage. After 4 time constants, a capacitor discharges 98.12% of the supply voltage. After 5 time constants, the capacitor discharges 99.3% of the supply voltage.
Easiest and most reliable way to ensure capacitor discharge is to permanently connect resistors across the capacitor terminals. As soon as power source is turned off, capacitor starts to discharge through the resistor. Discharge resistor can be externally connected or mounted inside the capacitor can.
Resistors are the preferred discharge device for capacitors though reactors and voltage transformers can also be used if faster discharge is necessary. By using resistor, the rate of discharge, resistor power dissipation can be controlled to a high degree by the designer.
Hight voltage capacitors should be discharged by using of a safe capacitor discharge tool. And one of them is a simple circuit using a wire and a light bulb (values 15W to 90W at the user’s convenience). Start with a setting up a multimeter to the highest DC voltage setting. Connect the leads of the capacitor to the multimeter probes.
