Understanding 'cathode' helps explain how devices like batteries work.

Device Function

'Cathode' is often associated with the negative (-) sign in diagrams or on devices.

Minus Sign

'Cathode' is a technical term used in physics-related fields and documentation.

Technical Context

The cathode in chemistry attracts positively charged particles, called cations.

Attraction Point

In discussions on chemistry, 'cathode' indicates a specific electrical charge context.

Charge Context

In electronics, 'cathode' explains the direction of electron flow in components like vacuum tubes.

Electronic Flow

The term 'cathode' is crucial for understanding how different electronic equipment operates.

Equipment Operation

 If the anode is at a slightly higher positive potential, the electrons are attracted to it, completing the circuit. This unidirectional current flow could be controlled by varying the voltage to the cathode, which makes it release more or less electrons.

 Reports were issued, so that this machine was cloned at 15 other places around the world. And it really was. It was the original microprocessor. All the computers now are copies of that machine. The memory was in cathode ray tubes --
