Definition

A type of electrode that has a negative charge and is used in various electrical devices, such as batteries and electron tubes, where it plays a role in the flow of electricity.

Example

In a battery, the cathode is where the reduction reaction takes place.

Conversation

Have you ever heard of a cathode in electronics?

Yeah, it's the part where the reduction happens, right?

Exactly! It's often used in batteries too.

I find it fascinating how different components work together.

Root Explanation

Cathode → It is formed from "cathodikos" (from Greek "kata" meaning down and "hodos" meaning way or path). The term refers to the electrode through which electric current flows out of a polarized electrical device, essentially the path going down in the circuit.

Memory Tip

Think of the 'down path' ('kata' means down and 'hodos' means way) to remember that a cathode is the electrode where current flows out.
