Voltage question......?
Air has a dielectric strength of 3 megavolts per meter. Consider a capacitor with a 1cm air gap. Find the maximum voltage that can be placed across it without having a spark jump the gap.
Do I just convert cm to m and multiply by 3?

Don't think so.
3 x 10^6 volts will send a spark across a 1 metre air gap.
so 3 x 10^4 volts (thats 1/100 th of the 3 x 10^6 ) will send a spark across a 1 cm air gap ( thats 1/100th of the 1 metre)
Thats it. Is that what you were planning? ;-)

30 kv per cm is the approved breakdown strength of dry air.
