- Measure current in high voltage (10kV) 2 answers
I have a circuit that will be using an ignition coil from a car to produce voltages in the range of 20kV to 30kV.
These will be arced across a gap and I'd like to measure the current across the spark gap.
Can I use a normal multimeter for this if the current is low? If not is there a cheap (<£15 including p&p) way to measure this current non-destructively?
PS I am in the UK at college and we need to keep our project under budget, and this is already proving difficult but we are very interested in the results of the experiment so we would rather not have to do something else.
