Definition

Describing a state of having no electrical power or energy, particularly in relation to alternating current where the current and voltage are out of phase.

Example

The device operated in a wattless state, meaning it consumed no real power.

Conversation

Have you ever heard of a wattless circuit?

No, I haven't! What does that mean?

It's when the current and voltage are out of phase, so it doesn't do any work.

That sounds interesting! I guess it makes sense in certain electrical contexts.

Synonyms & Antonyms

Root Explanation

Wattless → The word is formed from "watt" (named after James Watt, a Scottish inventor and mechanical engineer, representing a unit of power) and "-less" (meaning without). Therefore, "wattless" means without power measured in watts.

Memory Tip

Think of 'watt' as a measure of power and '-less' meaning without — so 'wattless' describes something that lacks power.
