In the experiment: To determine the resistivity of a semiconductor by using Four Probe method. If we can't use the temperature parameter here, like if the oven isn't working to heat the four probe setup. Can we still do the experiment by increasing the current and noting down the corresponding Potential? If so then how will that determine the resistivity? How will be carry out the experiment in this case. In the previous case we increased the temperature until it...
