Experiment 4: Ohm's Law Theory Ohm's Law states that the current, I, that flows through a resistor is directly proportional to the voltage, V, across the resistor and inversely proportional to the resistance, R: I = R In this experiment, we measure the current flow through the resistor, as we vary the voltage V and the resistance R.
