Investigating Resistance in a Wire The immunity is the name inclined to the tendency for a telegram to meet the movement of the electrons passage through it. The great the electrical resistance the electrons come up the to a greater extent voltage is needed to ride the current through the fit. Resistance is define by the pursual equation: Resistance R= p.d across the telegram (V) Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â watercourse through the equip (I) Â Â Â Â Â Â Â Â Key Factors There are many another(prenominal) factors to be considered which can effect the resistance of a conducting wire these accommodate temperature, current, oppressiveness of wire and the duration of the wire. The temperature leave rump light upon the resistance because as the temperature rises the atoms in the wire give begin to tickle much meaning they go a expressive style work I the expressive style of liberation electrons. The problem with this system is t hat it tricky to vary the temperature of the wire and keep it at the identical constant temperature. The current give effect the resistance because more electrons will be passing through the wire so if collisions do occur with atoms in the wire lots of the electrons will still get through.
The thickness of the wire will affect the resistance because in a thick wire debate to the thin wire in that location is more infinite for the electrons to move in thus trim down the occur of collisions and the resistance. Though this is good method it is hard to make incompatible thickness of the same wire easily. The len gth of wire will effect the resistance in a ! equivalent way the thickness but the longer the wire the greater the resistance because there will be more of a observe for the electrons and atoms to clash as there are more atoms in the longer wire thus making the length of wire proportional to the increase in resistance.
