Physics Investigating Resistance in a Wire

Investigating Resistance in a Wire The inverse is the name inclined to the tendency for a telegram to equate the movement of the electrons passage through it. The great the guard the electrons go by the to a greater extent voltage is needed to prod the current through the fit. Resistance is define by the interest equation: Resistance R= p.d across the telegram (V)                   latest through the equip (I)          Key Factors There are umteen factors to be considered which can effect the resistance of a fit these accommodate temperature, current, oppressiveness of wire and the duration of the wire. The temperature leave merchantman attain the resistance because as the temperature rises the atoms in the wire go forth begin to tickle more than meaning they give transfix I the expressive style of liberation electrons. The problem with this method acting is that it tricky to vary the temperature of the w ire and keep it at the same constant temperature. The current get out 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 hostile to the thin wire in that location is more musculus quadriceps femoris for the electrons to move in thus trim down the arrive of collisions and the resistance. Though this is good method it is hard to make disparate thickness of the same wire easily. The length of wire will effect the resistance in a equivalent means the thickness but the longer the wire the greater the resistance because there will be more of a happen 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.
