Question

How do you calculate voltage drop in a series circuit?

Answer 1

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*R`, which tells us to then multiply `I" by "R`. E is the voltage across the component also known as voltage drop.
