  2. Electrical resistance and conductance - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistance_and...

    Running current through a material with resistance creates heat, in a phenomenon called Joule heating. In this picture, a cartridge heater, warmed by Joule heating, is glowing red hot. Resistors (and other elements with resistance) oppose the flow of electric current; therefore, electrical energy is required to push current through the resistance.

  3. Integrated circuit design - Wikipedia

    en.wikipedia.org/wiki/Integrated_circuit_design

    Integrated circuit design involves the creation of electronic components, such as transistors, resistors, capacitors and the interconnection of these components onto a piece of semiconductor, typically silicon.

  4. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    An electric current is a flow of charged particles, [1] [2] [3] such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.

  5. Coupling (electronics) - Wikipedia

    en.wikipedia.org/wiki/Coupling_(electronics)

    In electronics, electric power and telecommunication, coupling is the transfer of electrical energy from one circuit to another, or between parts of a circuit. Coupling can be deliberate as part of the function of the circuit, or it may be undesirable, for instance due to coupling to stray fields.

  6. Noise (electronics) - Wikipedia

    en.wikipedia.org/wiki/Noise_(electronics)

    Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.

  7. Metal electrode leadless face - Wikipedia

    en.wikipedia.org/wiki/Metal_electrode_leadless_face

    Despite their handling difficulties, and in the particular case of MELF resistors, they are still widely used in high-reliability and precision applications where their predictable characteristics (e.g., low failure rate with well-defined failure modes) as well as their higher performance in terms of accuracy, long-term stability, moisture resistance, high-temperature operation far outweigh ...

  8. Nodal analysis - Wikipedia

    en.wikipedia.org/wiki/Nodal_analysis

    Kirchhoff's current law is the basis of nodal analysis. In electric circuits analysis, nodal analysis, node-voltage analysis, or the branch current method is a method of determining the voltage (potential difference) between "nodes" (points where elements or branches connect) in an electrical circuit in terms of the branch currents.
