... Resistance of a Wire Investigation Plan Electricity is the flow of free electrons in a metal. These electrons usually move randomly through an atom but when a charge is added the metal gains positive and negative ends. The electrons are attracted to the positive ends. Other atoms in the metal will slow down the electron and it will 'bounce' around in the metal until it reaches the positive end of the wire. The longer it takes and the harder you have to push for the electrons to reach the end the higher the resistance of the metal. atom atom Metal Wire - + electron electron The voltage of a circuit is how much power is being run through it. The higher the voltage gets, the more you are having to push to make the current move. The current is the flow of the electricity in the actual circuit, due to the number of electrons mowing around
