You rearrange this to get a result for resistance (that is R=E/I). You measure a voltage of 5 volts and an amperage of 1 amp across an unknown resistor. Using *Ohm's law*, the resistance must be positive or plus 5 ohms (R=E/I, R=5 V/ I A= 5 Ohms). Graphing the current and voltage would generate a straight line and the slope of **…**
