I have an 8pF capacitor charged to 8V. How can i measure which end is positively charged assuming i have a small amount of cash and a local electronics store.
This seems tricky since it has only a tiny amount of charge.
Could i for example:
- see a brief flash from a connected Led?
- see a momentary needle movement on an analogue ammeter when shorted?
