Physics, science 1 Investigation- Experiment to Find out the factors that effect resistance in a Wire Scientific Basis An electrical current can pass through a metal because the electrons in the outer shell of the wires' atoms are allowed to flow freely throughout the wire. So when you place a Cathode (negatively charged) on one end of a wire and an Anode (positively charged) on the other and allow an electrical current to pass through, the electrons can move freely between the Anode and the Cathode Resistance occurs when the negatively charged electrons travelling through a wire a wire, from the Cathode to the Anode, collide with the atoms of the wire. There are several factors that affect the level of resistance produced by a wire, these are: * Temperature; when the atoms and the wire are heated up, the atoms will vibrate because of their increase in energy. This will cause an increase in...
