Turn the voltage clockwise until the voltage display is approximately 7.2 V (7–7.5 V is acceptable). ... Use the following formula to determine how many joules (J) of work it took to lift the weight in the system. As you carry your units through to the solution, change the final answer from N∙m to the equivalent J.
