I need a circuit to tell me when my capacitors are charged to around 200V or 400V, am i correct in thinking i can use a potential divider with high value resistors and a neon bulb, the resistor values chosen to give a voltage of 70-95V(i think this is the strike voltage for most neon bulbs)

what kind of current do neons pull?, i wanted to use high value resistors to keep the current flow from the capacitors to a minimum.

are there any other possible indicators other than neons, perhaps LED's??

Thanks.

Thanks for the reply Nigel

I will source a few neons and experiment a little.

Are there any other options???

What a coincidence, this is what i am using my capacitors for and this why i need to know when they are charged, i think i will go for a neon.

Thanks Nilgel
