Investigating the granting immunity of Nichrome telegram. Aim In this investigation, I am going to be invstigating how the space of Nichrome outfit come tos the enemy that is applied. expectation In 1826, Georg Ohm discovered that the current flowing by dint of a metal wire is proportional to the potentail difference crossways it, it basically means if you epitome the potential difference you double the current. The abbreviate wire in a lamp tends to resist the straw world of electrons in it, this means that the wire has a certain ohmic underground to the current. The greater the resistance, the more potency is needed to push a current 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 scrap 18 four factors affecting resistance they be: 1) As the duration increases, the resistance increases 2) As cross-sectional area increases, the resistance decreases 3) slob is a go od conductor 4) As temperature increases, the resistance of a wire increases Using the information above I will be able to attempt an idea what my results would scent like after I do the experiment. I regard that As the length of the wire increases so does the resistance, one of the four factors that affect resistance of wire is as the length increases, the resistance increases, this repoint that my prediction may be right.
Apparatus Below are the apparatus that I will be apply: 1)Nichrome fit out 2)Cell: Power supply 3)Variable Resistor: To fine tune the voltage 4)Voltmeter: To amount the vol tage 5)Ammeter: To mea authentic the current! 6)Ruler: To measure wire length 7)Wires A pilot experiment is when you do a experiment before you do the real experiment to abridge out that it would be a fair test and to give way sure everything is in working order.
