The operation V ÷ I in electrical terms specifically represents the calculation of resistance. This is derived from Ohm's Law, which states that V = I × R, where V is voltage, I is current, and R is resistance. Rearranging this equation gives R = V/I, demonstrating that resistance can be determined by dividing voltage by current.

Resistance is measured in ohms (Ω), and it quantifies how much a circuit resists the flow of electric current. When you perform V ÷ I, you are essentially determining how much resistance is present in the circuit when a certain voltage is applied across it, and a certain current is flowing through it.

The other options such as current, voltage, and power stem from different relationships in electrical circuits—current indicates the flow of charge, voltage represents the potential difference, and power is the rate at which work is done or energy is transferred in a circuit. However, V ÷ I directly leads to resistance, confirming that this operation quantifies how tightly the electric current is constrained in its flow by the circuit components.
