  2. List of resistors - Wikipedia

    en.wikipedia.org/wiki/List_of_resistors

    Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components ...

  3. Resistor - Wikipedia

    en.wikipedia.org/wiki/Resistor

    Various resistor types of different shapes and sizes. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

  4. Electronic circuit - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit

    It is a type of electrical circuit. For a circuit to be referred to as electronic, rather than electrical, generally at least one active component must be present. The combination of components and wires allows various simple and complex operations to be performed: signals can be amplified, computations can be performed, and data can be moved ...

  5. Voltage-controlled resistor - Wikipedia

    en.wikipedia.org/wiki/Voltage-controlled_resistor

    Voltage-controlled resistors are one of the most commonly used analog design blocks: adaptive analog filters, [1] automatic gain-control circuits, clock generators, [2] compressors, [3] electrometers, [4] energy harvesters, [5] expanders, [6] hearing aids, [7] light dimmers, [8] modulators (mixers), [9] artificial neural networks, [10] programmable-gain amplifiers, [11] phased arrays, [12 ...

    An ohmmeter could be used to verify this value. Substances in which electricity can flow are called conductors. A piece of conducting material of a particular resistance meant for use in a circuit is called a resistor. Conductors are made of high-conductivity materials such as metals, in particular copper and aluminium. Resistors, on the other ...

  8. Pull-up resistor - Wikipedia

    en.wikipedia.org/wiki/Pull-up_resistor

    In electronic logic circuits, a pull-up resistor (PU) or pull-down resistor (PD) is a resistor used to ensure a known state for a signal. [1] It is typically used in combination with components such as switches and transistors, which physically interrupt the connection of subsequent components to ground or to V CC.

  9. Ohm's law - Wikipedia

    en.wikipedia.org/wiki/Ohm's_law

    Ohm's law, in the form above, is an extremely useful equation in the field of electrical/electronic engineering because it describes how voltage, current and resistance are interrelated on a "macroscopic" level, that is, commonly, as circuit elements in an electrical circuit. Physicists who study the electrical properties of matter at the ...
