Capacitor Safety Discharge Calculator
About:
This Capacitor Safety Discharge calculator helps to determine the discharge rate of a capacitor at known capacitance and charge. Many factors need to be considered when choosing a discharge resistor. Safety standards require the voltage across a capacitor to reach a safe voltage before a person is able to touch it. In the USA, standards such as UL, OSHA, NTA, ETL, MET, etc. will have the requirements available for the needs of your product.
