If I equals V divided by R, what quantity does this equation solve for?

Explanation:
The quantity determined by I = V/R is current. This form of Ohm’s Law shows how current depends on the voltage across a resistor and the resistor’s opposition to flow (the resistance). Voltage divided by resistance gives amperes, so when you plug in voltage and resistance, you’re solving for how much current flows. If you wanted to solve for voltage, you’d rearrange to V = IR; for resistance, R = V/I; and power relates by P = VI or P = I^2R, which are different expressions.
