Investigating Resistance in a Wire The resistance is the name given to the tendency for a wire to oppose the movement of the electrons passing through it. The greater the resistance the electrons occur the more voltage is needed to propel the current through the wire. Resistance is defined by the following equation: Resistance R= p.d across the wire (V) <Tab/><Tab/> Current through the wire (…showed first 75 words of 598 total…

…showed last 75 words of 598 total…there is no variation in the apparatus. Preliminary work After conducting a preliminary experiment I have arrived at many conclusions. As a result of these findings I have altered my method to deal with any problems. Firstly when trying to set up the wire I encountered the problem of the coiling or touching an object. To deal with I have decided to wrap the length of wire so it will be unable to touch itself.
