Electric Current and Circuits PowerPoint
... • When a wire connects the terminals of a battery or generators, then the voltage will push and pull electrons through a conductor. – One terminal has extra electrons thus a negative charge. The other terminal has a deficit of electrons and thus a positive charge. – Electrons in the wire are pushed ...
