Hey. I'm invesitgating how resistance in a nichrome wire is affected by the length of wire. Please check my prediction for me: "I predict that when I increase the length of wire, the resistance in the circuit will increase. This is so as there are more atoms in the wire for the electrons to collide with in a longer wire, stopping electrons and creating resistance. As the wire increases in length, there are more atoms, so as the electrons flow through the wire, the greater number of atoms causes a higher resistance. There are more ‘barriers’ and ‘obstacles’ for electrons to pass. The voltage (the electric potential difference between two points) therefore increases. As electrons pass through the wire, they collide with the high number of atoms and transfer kinetic energy over to them. As atoms are fixed and can just vibrate, the additional energy they receive results in the kinetic energy to be transferred into heat energy, thus resulting in a high temperature of wire." I wrote that myself and all I'm asking you is to see if that is all scientifically correct. Any other stuff to add would be nice though. Thanks.
