Just as Ohm's law basically demonstrates how amperage (current flow), voltage (electrical pressure), and resistance (opposition to current flow) all relate to each other, It's Lenz's law that allows us to view the functionality of the components in the electrical circuit. Just because a command was given doesn't mean a function was carried out. If you don't believe me, simply instruct your child to clean his or her room, and you'll quickly realize a command doesn't always produce the intended goal. |
