Vi Graph Of Two Wires A And B. I think the point of the problem is given that the graphs are straight lines how do the temperatures of the wires. Aug 29 2019 When wire is bent back and forth the deformations are beyond elastic limit.
When we consider the graph given the gradient of the wire A has a higher inclination which means its gradient is higher than that of wire B. Give justification for your answer. V I graph for two wires A and B are shown in the figure.
Most students do not know how to plot a graph between two variables.
ρ Al 263 x 10-8 Ω m ρ Cu 172 x 10 8. However the scale is not shown so the graphs could be straight if say the voltage range is 0 - 1 mV. Greater than slope of V-I graph greater will be the resistance of given metallic wire. Determine the slope of the graph.
