Definition

A metal mixture made of nickel and copper, known for maintaining a steady electrical resistance even when temperatures change.

Example

Constantan is often used in thermocouples to measure temperature accurately.

Conversation

Have you ever heard of constantan?

Yeah, isn't it that alloy used in electrical instruments?

Exactly! It's known for its stable resistance with temperature changes.

That's pretty cool; I didn't know it was made of copper and nickel!

Synonyms & Antonyms

Root Explanation

Constantan is a metal alloy composed primarily of copper and nickel, and the name is derived from the word 'constant' (from Latin 'constans', meaning standing firm or stable) and the suffix '-an' (indicating a material). The term 'constantan' refers to the stable electrical resistance of this alloy, which remains relatively constant over a range of temperatures.

Memory Tip

Think of 'constant' as something that remains 'stable' or 'unchanging' — that's why constantan is known for its stable electrical resistance.
