In a circuit, current I can be calculated as I equals P divided by V. Which expression represents this relationship?

Explanation:
Power in a circuit is related to voltage and current by the equation P = V × I. That means current is the power divided by voltage. Solving for I by dividing both sides by V gives I = P / V, so the expression that represents this relationship is P divided by V. The other forms don’t give current: V/P would have the wrong units for current, P × V combines power and voltage into a product that isn’t current, and V × I already equals power, not current.
