Amplifier

Push-pull switch

Consumer electronics; Amplifier

A switch that is operated by a pulling or pushing movement; often combined with a potentiomenter.

A load that contains inductance or capacitance, either with or without resistance as well. An example of a reactive load is a loudspeaker which has an impedance that varies with frequency, unlike a ...

Rectifier

Consumer electronics; Amplifier

This is the same thing as a diode, but the term is usually reserved for diodes used in the power supply section of an amplifier.

Reflected impedance

Consumer electronics; Amplifier

The impedance seen "looking into" the primary of a transformer when it the secondary is loaded with a specific impedance. The impedance on the secondary side is transformed by the square of the ...

Resistive load

Consumer electronics; Amplifier

A load that contains no inductance or capacitance, just pure resistance An example of a resistive load is a dummy test load consisting of a single resistance equal to the output impedance of the ...

Resistor

Consumer electronics; Amplifier

A circuit element that presents a resistance to the flow of electric current. A current flowing through a resistance will create a voltage drop across that resistance in accordance with Ohm's law.

RMS (root mean square)

Consumer electronics; Amplifier

The true measure of an amp’s ability to perform, RMS is based on continuous power at a given number of cycles per second over a period of time not less than 30 seconds. See Peak.
