Old Appy,

I'm a little unclear on that also. I'm wondering where the Energy comes from that is released as Heat or Light etc. as current passes through it. It seems like something should be depleted somewhere. I don't think electrons get 'lost' but they may give up their energy and stop flowing. Or, what I'm thinking is that some of them may pass their energy, say to electrons in a Lightbulb filament which in turn give off Light and Heat.

Less Electrons flowing means lower voltage. (I = E/R) So in the case of a set amount of pressure (voltage) as in a Battery, Current and Voltage will eventually drop off.

Anyone, Does this seem right?

Be kind.... [Linked Image]
