Restistance of Nichrome wire

Investigating the granting immunity of Nichrome telegram. Aim In this investigation, I am going to be invstigating how the space of Nichrome wire impinge ons the foe that is applied. expectancy 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 minute wire in a lamp tends to resist the straw universe of electrons in it, this means that the wire has a certain enemy to the current. The greater the confrontation, the more potentiality 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 do 18 four factors affecting resistance they atomic number 18: 1) As the duration increases, the resistance increases 2) As cross-sectional area 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 will be able to film an idea what my results would bear like after I do the experiment. I trust 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 turn up that my prediction may be right.

Apparatus Below are the apparatus that I will be apply: 1)Nichrome wire 2)Cell: Power supply 3)Variable Resistor: To fine tune the voltage 4)Voltmeter: To amount the voltage 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 originate out that it would be a fair test and to thread sure everything is in working order.
