1. The problem statement, all variables and given/known data Given that the unit of current is related to the units of electric charge and time by A = C/s, and the unit of voltage is related to the units of energy and charge by V = J•C^-1, express the power in terms of these other units. Simplify the result further, given that the watt (W) is defined by W = J/s 2. Relevant equations A = C/s V = J•C^-1 3. The attempt at a solution W = C/s • J•C^-1 W = J/s Now what? I don't understand what the question is asking.
