Simple Explanation

The thing that uses power from an audio system, like a speaker connected to an amplifier.

Concise Technical Definition

A component or device that receives and consumes electrical power from a source; typically characterized by its impedance in audio systems.

Layman-Friendly Analogy

Like a lightbulb plugged into a socket—it’s the thing that uses the power.

Industry Usage Summary

In audio, the load is usually a speaker connected to an amplifier. The impedance of the load affects how much power is drawn and can impact system performance or amplifier stability.

Engineering Shortcut

Power-receiving device (e.g., speaker); defines system impedance.

Full Technical Explanation

In electrical and audio systems, a load is any device that receives power from a source and converts it into another form (e.g., sound, heat, light). In audio, the most common load is a loudspeaker, which draws current from an amplifier. The electrical impedance of the load, measured in ohms (Ω), determines how much power is transferred from the source. Mismatched loads (too low or too high impedance) can cause distortion, overheating, or even equipment failure. Accurate load matching is critical in amplifier design, speaker selection, and system optimization.
