Which equation correctly represents Ohm's Law?

Ohm's Law describes how voltage, current, and resistance relate in an electrical conductor. The voltage across a component equals the current through it times its resistance, so the correct equation is voltage = current × resistance. This shows why increasing current through a fixed resistance raises the voltage proportionally, or why increasing resistance requires a higher voltage to push the same current. The units line up cleanly: volts equal amps times ohms. The other expressions mix in different concepts or use different symbols without expressing that direct V–I–R relationship—for example, a power formula or an alternative symbol for voltage that isn’t the standard form for a resistor.
