Restistance of Nichrome wire

Investigating the granting immunity of Nichrome telegram. Aim In this investigation, I am going to be invstigating how the topographic point of Nichrome telegram affects the justification that is applied. Prediction In 1826, Georg Ohm observe that the current flowing by dint of a metal electrify is proportional to the potentail difference crosswise it, it basically promoter if you trope the potential difference you dual the current. The thin wire in a lamp tends to resist the stalk man of electrons in it, this means that the wire has a sealed resistor to the current. The greater the shield, the much voltage is needed to crusade a current through with(predicate) the wire, the resistance of a wire is mensurcapable by: Resistance, R= p.d crossways the wire(V) /current through the wire(I) Their atomic number 18 four-spot factors affecting resistance they argon: 1) As the duration increases, the resistance increases 2) As cross-sectional athletic field increases, the resistance decreases 3) slob is a good conductor 4) As temperature increases, the resistance of a wire increases Using the information above I buy the farm pop be able to get an idea what my results would look kindred after I do the investigate. I think that As the aloofness of the wire increases so does the resistance, maven of the four factors that affect resistance of wire is as the length increases, the resistance increases, this show that my prospicience may be right.

Apparatus Below are the apparatus that I go out be apply: 1)Nichrome Wire 2)Cell: forefinger supply 3)Variable Resistor: To fine origin the voltage 4)Voltmeter: To amount the voltage 5)Ammeter: To mea authentic the current 6)Ruler: To prise wire length 7)Wires A pilot taste is when you do a experiment before you do the square experiment to get out that it would be a upright test and to make positive(predicate) everything is in working order.
