Capacitors explode violently when mistreated. You could lose an eye or even worse.

Yes, I know that, But a nonpolarized capacitor rated for 330VAC can explode it I charge and discharge with 6 VAC?

Not likely but what do you hope to discover by conducting this experiment?

 

If it is possible to connect a capacitor to an AC power supply and when diconect it is discharged because I did it in the moment that the current changes its path. It occurred to me just after the firts post. Later some people confirmed that.

 

It seems like Rufinus does know what he's talking about. But those bare mains wires might make some people nervous.

Yes, I understand, first I connect the alligators, and then I plugged the plug in the 220VAC sockect. I don´t even try to manipulate the alligators if there are connected to 220VAC

Not enough for the Awards but it is a start.

Every time you disconnect the AC voltage there is no way of knowing the phase at the time of disconnect.
Your voltage reading across the capacitor is unpredictable.

Yes, that is what I want to check.

If you disconnect it at the moment that the current changes direction the capacitor will NOT be discharged, it will be charged to its greatest degree and hence have the highest magnitude of voltage across it.

In order to disconnect it and have it be discharged you would need to disconnect it at the moment that it is at the greatest current because that is what is happening as the voltage passes through zero.

 

Ah, yes, I forgot the 90º delay between current and voltage, thank you

 

At 50Hz the AC voltage has a period of 20ms. In order to disconnect the capacitor at a particular phase angle you would need an electronic circuit. You cannot do this manually.

There are some things you cannot check experimentally without special equipment and you simply have to accept theory.

 

I don't think he was trying to disconnect at a particular phase angle, but was rather doing what amounts to a Monte Carlo experiment by making a lot of random measurements and noting whether the observed behavior is in line with what theory predicts.

 

Yes yes, I know that is almost impossible have the capacitor completely uncharged with that method, but the results (Different polarities and voltages) confirm my theory.
