How to calculate current from capacitor
How much current does a capacitor draw when charging?
I''m using a large capacitor to buffer the load requirement of a solenoid (solar/battery operated setup, with solenoid kicking in a few times a day). Someone mentioned that if I use a large-enough $begingroup$ It has 2 components, when initially turned ON, inrush current exists, which depends on ESR of your cap and dV/dT of turn …
voltage
Once the capacitor is charged in your circuit, no current will flow. If the capacitor is fully discharged, then the current at the start will be 100 V/8 Ω = 12.5 A, but since the power supply can only deliver 5 A you will only get 5 …
