Provides the current that powers speakers. Usually, well designed amplifier circuits deliver high continuous current in relation to their nominal power rating. Well designed, low powered receivers can sound more dynamic and powerful than competing units with two to three times the power. This can happen when a receiver has less current capability. An amplifier's current capability is a function of power supply engineering and storage capacity. Standard amplifier ratings are determined by connecting an amplifier to a precise 8-Ohm resistor, such an arrangement incurs low level demands for current. For example, a 40-volt output into an 8-Ohm resistor can generate 100 watts of power with less than 3 amperes of current.

In the case of audio power amplifiers, they are usually referred to in Watts (a unit of power) into a specified load impedance, usually 2, 4 or 8 ohms. It is important to point out that not all manufacturers rate their amplifiers in the same way or at the same impedance.
