As the current approaches the end of the wire but has no place to go, the charges pile up until they are pushed back in the other direction. By the time it's back, it's travelled \$\lambda/2\$ or experienced a \$180^\circ\$ phase shift. philam life roxas city

WebMar 4, 2024 · The AC current in a typical house circuit does not flow through earth. For 120 volt circuits, it flows through one of the 120 volt wires (normally black) and returns through the neutral wire (normally white). For 240 volt loads, the current flows from one of the 120 volt lines to the other 120 volt line. WebTo return to your original question, electricity travels more freely through wires because wires are very dense and contain a large number of highly mobile electrons.
