The Truth About Long Wires and Electrical Energy Flow

TLDRLong wires in a circuit do not affect the time it takes for the current to flow, but they do affect the amount of current. The energy in a circuit flows through electromagnetic fields, not the electrons themselves. The flow of energy can be modeled using inductors and capacitors. The waves of fields traveling through the wires reflect and add up to the energy going into the load. The impedance of a long wire circuit is equivalent to a resistor.
