Conversation

I learned about this thing called a busbar in my electrical engineering class.

Oh, really? What does it do?

It's basically a conductor that carries a lot of current, usually made of copper or aluminum.

That sounds interesting! I didn't know that was how power distribution works.

Root Explanation

Busbar → The word is formed from "bus" (short for "omnibus" from Latin *omnis*, meaning all) and "bar" (from Old English *bær*, meaning a solid piece). A busbar is a solid piece that conducts electricity to all parts of a system.

Memory Tip

Think of 'all' ('omnis') being connected by a 'solid piece' ('bar') — that's how a busbar distributes electricity to all parts.
