Multiply the resistance of the component by the current thru it.

Explanation:

To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it.

Ohm's Law is E = I*RE=I⋅R, which tells us to then multiply I" by "RI by R. E is the voltage across the component also known as voltage drop.

I hope this helps,
Steve
