How to Charge Capacitor Without Resistor?
It depends on the capacitor. Some capacitors can hold a charge for days, while others will only hold a charge for hours. Certain types of film capacitors can even hold a charge for years! A lot of factors can affect how long a capacitor can hold a charge, including the type of capacitor, the temperature, and the amount of current.
