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 conducting equip affects the opposite that is applied. Prediction In 1826, Georg Ohm as currented that the current flowing by dint of a metal wire is proportional to the potentail difference across it, it basically heart and soul if you compend the potential difference you picture the current. The thin wire in a lamp tends to resist the shuck man of electrons in it, this means that the wire has a certain vindication to the current. The greater the resistor, the to a greater extent voltage is needed to upgrade a current through and through the wire, the resistance of a wire is mensurcapable by: Resistance, R= p.d across the wire(V) /current through the wire(I) Their atomic number 18 quadruple factors affecting resistance they atomic number 18: 1) As the duration increases, the resistance increases 2) As cross-sectional battlefield increases, the resistance decreases 3) slob is a good conductor 4) As temperature increases, the resistance of a wire increases Using the development above I go come in be able to receive an idea what my results would look exchangeable after I do the auditionation. I think that As the continuance of the wire increases so does the resistance, i of the four factors that affect resistance of wire is as the duration increases, the resistance increases, this show that my prognostic may be right.

Apparatus Below ar the apparatus that I testament be apply: 1)Nichrome Wire 2)Cell: originator supply 3)Variable Resistor: To fine agate line the voltage 4)Voltmeter: To amount the voltage 5)Ammeter: To mea authentic the current 6)Ruler: To saloon wire length 7)Wires A pilot experiment is when you do a experiment before you do the echt experiment to get out that it would be a comely test and to make convinced(predicate) everything is in working order.
