Yep. And if it's a paper cap, it'll often be leaky as the dickens. No
criticism taken but I was talking of using _only_ an AC/DC set to do the
hot-chassis illustration to his girlfriend (or anybody else for that
matter). A rather dramatic illustration, which BTW eliminates the capacitor
influence, is to use a 120volt incandescent light bulb between the hot
chassis and the sink faucet. Any wattage bulb would do but a 100-watter
will light up brightly and drive the point of the shock risk home a bit
more so than a measly 40-watter.
