ParanoiA Posted March 2, 2011 Share Posted March 2, 2011 I've got myself turned around apparently. I thought voltage was the potential difference between oppositely charged poles - that voltage is a measure of the difference in charge carriers. I'm envisioning ionized clouds of opposite charge and I thought that the amount of voltage between the two would depend on the amount of the difference in charge between the two - that the amount of voltage would depend on the number of charge carriers. But somewhere in that bit up there I'm apparently off. Because you can have high voltage with only a small amount of charge carriers, or a small voltage with a high quantity of charge carriers. I'm not getting that at all and it's making my intuition cry. And I've been through the water pipe analogies, and I actually do get the "pressure" concept. But with water pipes I can see where 'pressure' comes from and I can imagine a pint of water under 200 lbs of pressure. But I cannot "see" where voltage is coming from, and I cannot imagine a trickle of current from a thousand volts of 'pressure'. (please note, I'm not talking about resistance and insulating materials that restrict the flow of charge carriers, rather I'm assuming a perfect conductor). Can anyone see where I'm going conceptually wrong here? Link to comment Share on other sites More sharing options...
