Ohm's law Ohm's law In this activity, you explore the difference between electric current and electric potential. You are given the equation: V=IR In this activity, V, voltage ranges from 0.1 V to 9 V. Resistance, R, ranges from 10 to 1000 2. The unit of resistance is the ohm, and the symbol used is the Greek capital letter omega, Q. When the resistance is set at 500 Q, and voltage at 3.4 V, the current is 6.8 mA. When resistance is kept the same, and the voltage is changed to 7.5V, the current is 15.0 mA. What the experiment illustrates is that the current is very small. Also, the resistance and the current have an inverse relationship: an increase in resistance results in a decrease in current.
