HOW DOES THE LENGTH OF THE WIRE AFFECT THE RESISTANCE PLANNING Prediction I predict that the longer the wire is, the more resistance there would be therefore the less current that would pass through. As voltage is directly proportional to current, I predict that my graph showing the resistance will look like this: Scientific Explanation An electric current will flow through an Electrical Component (or device) if there is a voltage across the ends of the component. Resistance is a measure of how hard it is to get a current through a component at a particular voltage. Voltage current and resistance are related by the equation: VOLTAGE (V) = CURRENT (A) X RESISTANCE (?) Resistance occurs because as electrons pass along a wire they collide with atoms of the metal and so lose energy. The longer the conductor, the more particles there are in the way and so the harder the electrons find it to flow. In...
