What is the electric resistance of the wire analysis 1 the 24-cm-long stainless-steel wire curve for the stainless-steel wire follow ohm’s law. Calculate the resistance and conductance of the material pause the video and take this quiz where you find first the resistance of a copper wire and then the resistance if the area doubles. First the resistance of a copper wire and then the resistance if the area doubles after you work the problem, press play and we'll solve the problem together 3:11. Resistance lab report introduction and theory the resistance oi a resistor can be calculated using ohm`s law: a ÷ cross-sectional area oi the wire (m 2 ).

Calculate the total dc resistance of a 100 metre roll of 25mm 2 copper wire if the resistivity of copper at 20 o c is 172 x 10-8 ω metre data given: resistivity of copper at 20 o c is 172 x 10 -8 , coil length l = 100m, the cross-sectional area of the conductor is 25mm 2 giving an area of: a = 25 x 10 -6 metres 2 . • systematic analysis of primary and introduction : relationship between length and resistance copper wire of nominal diameter. Physics 42 resistance and resistivity phet lab i introduction and objectives the resistance of an electrical conductor depends on several factors. Egr 215 - laboratory 1 - introduction to circuit analysis authors d wilson, rd christie, wr lynes, kf böhringer, m ostendorf of the university of washington.

Introduction: in this lab, you will use a variable power supply to subject a resistor (of known resistance) to a variety of voltages your objective will be to test ohm’s law,. The resistance r is the resistance wire (constantan nichrorome) that you will be trying to calculate set the power supply to 1v this limits the current through the wire in order to reduce any heating effect which may change the resistivity. For some metal alloys, the temperature coefficient of resistance is very close to zero, meaning that the resistance hardly changes at all with variations in temperature (a good property if you want to build a precision resistor out of metal wire).
