Definition

Relating to the negative electrode in an electrical device, where electrons flow into the device.

Example

The cathodic protection system helps prevent corrosion in pipelines.

Conversation

I just learned about cathodic protection in my science class.

Oh really? What does that involve?

It's basically a way to prevent corrosion using a negative electrode, like a cathodic system.

That sounds interesting! I had no idea that was a thing.

Root Explanation

Cathodic → It is formed from "cathode" (from Greek "kathodos", meaning way down or descent) and the suffix "-ic" (meaning pertaining to). The word "cathodic" refers to something that is related to or characteristic of a cathode, which is the electrode through which current flows into a polarized electrical device.

Memory Tip

Think of 'kathodos' meaning 'way down' to remember that 'cathodic' relates to the electrode where current flows in, often associated with a downward direction in electrical circuits.
