To find the voltage drop across a component, you multiply the current by

Explanation:
Ohm's law connects voltage, current, and resistance. The voltage drop across a component is the current through that component multiplied by its own resistance, so you use the component’s resistance in the calculation. The current alone wouldn’t set the drop unless the resistance happened to be 1 ohm, and the source voltage isn’t necessarily the drop across that component since other elements can share the supply. The total resistance helps determine current for the whole circuit, not the specific voltage drop across one part.
