  2. Constant-voltage speaker system - Wikipedia

    en.wikipedia.org/wiki/Constant-voltage_speaker...

    Multiple amplifiers can be combined together via transformers to yield higher voltage and higher current capacity lines. For instance, three 70-volt amplifiers have been used to make a 210-volt line by connecting them to a special-purpose external output transformer that has three primaries and a single secondary.

  6. Instrumentation amplifier - Wikipedia

    en.wikipedia.org/wiki/Instrumentation_amplifier

    Typical instrumentation amplifier schematic. An instrumentation amplifier (sometimes shorthanded as in-amp or InAmp) is a type of differential amplifier that has been outfitted with input buffer amplifiers, which eliminate the need for input impedance matching and thus make the amplifier particularly suitable for use in measurement and test equipment.

  7. Electronic circuit - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit

    A circuit diagram representing an analog circuit, in this case a simple amplifier. Analog electronic circuits are those in which current or voltage may vary continuously with time to correspond to the information being represented. A simple schematic showing wires, a resistor, and a battery

    Because cancer cells take up more glucose than most other healthy cells, they light up in the images.” “Glucose and fructose are made up of the exact same atoms,” he continued.

  9. Bridged and paralleled amplifiers - Wikipedia

    en.wikipedia.org/wiki/Bridged_and_paralleled...

    Representative schematic of a paralleled amplifier configuration. A paralleled amplifier configuration uses multiple amplifiers in parallel, i.e., two or more amplifiers operating in-phase into a common load. In this mode the available output current is doubled but the output voltage remains the same. The output impedance of the pair is now halved.
