WebNow discuss with the class the model of resistance as arising from collisions between moving charges and the particles in the wires through which the current moves (i.e. the ‘particle collision’ model of electrical resistance). How will the introduction of a second bulb influence the current flow and brightness of the first bulb? WebThe resistance of a wire is affected by the: Length of the wire; Thickness of the wire; Length. If a metal wire is longer, electrons from an electric current with collide with more ions from the metal, as they flow through the wire. The increased collisions make it harder for current to flow through, meaning the resistance will increase.
