Learning RC capacitor charging

01:59:35

Closing the switch charges the capacitor and when opening the switch you can see the capacitor drain away. Haven’t made the led light up yet - still working on that.

Is RV charging less efficient then SU charging?

oops I've renamed this project to RC (resistor + capacitor) because the reference to RV was a typo. Not sure what RV and SU charging is - am only a beginner!

Lower the resistors to 400 ohms

@eschler407- thanks, I've made the change and the LED now lights up when the switch is on. Great! But when the switch is off, the LED doesn't stay on and get powered by the capacitor. I tried lowering the resistor preceding the led but that didn't help.
