Hi, I'm using this here metronome to test capacitors. you just plug the capacitor into the socket, and depending on the value, the speaker will produce a series of clicks, or whine.
When I plug a .01 uf capacitor into the circuit, it will buzz, which is normal. Then when I plug a .047 uf cap into it, it melted the bloody speaker, and the transistors got very hot. Anyway, I take it that this means the capacitor is bad, but why does it do this?
Is using a metronome a good way to test capacitors?
P.S. sorry for the cruddy drawing. does anyone know how to publish a picture using the simulation program Crocodile Tech?
