Contact UsHow can there be a voltage when there is no current?
Large voltage at zero current! Blasphemy!!! So, if voltage isn''t caused by current, what then causes voltage? Simple: electric charge causes voltage, since electric charge is permanently associated with e-fields, and voltage is simply a description of e-fields. The misconception about current causing voltage seems to have a specific origin.

Contact UsHow a battery works
Current = the number of electrons that happen to be passing through any one point of a circuit at a given time. The higher the current, the more work it can do at the same voltage. Within the cell, you can also think of current as the number of ions moving through the electrolyte, times the charge of those ions. Power = voltage x current.
