How to Charge Capacitor Without Resistor?
If less, then you need some resistance to limit current while charging up the caps. For example, 100uF 50V electrolytic will take about 17 seconds to reach 63 volts (50+15) because of internal ESR ... When charging a capacitor, you can use a resistor to limit the current. The size of this resistor will depend on the voltage and capacitance ...
