Rearrange Ohm's law

Show the conversion and the equation. A few sentences plus the numbers is enough.

A bulb is labeled 4.0 Ω and carries 500 mA. Find the battery voltage. In your answer, convert the current to amperes before substituting, and name the Ohm's-law form you used.

500 mA is not 500 A. V = IR after the conversion.
