We measured the current I and the voltage V for the 4 resistances.I tabulated the results in the table below, and calculated the resistance "R" using the values for V and I.Next, we measure the actual value of the resistance "Rm" using a digital millimeter. The values of ΔV, ΔI and ΔRmwere provided beforehand.V - 2V (V)I (mA)0.8010.001.6220.002.4330.003.2640.004.0850.00I also added error bars to the line to indicate the accuracy with which the current can be measured at the given voltage.I plotted the data obtained in the table given below.For the next experiment, we selected the second largest resistance and measured the value for V using 5 different values of I....
