  2. Flux linkage - Wikipedia

    en.wikipedia.org/wiki/Flux_linkage

    In circuit theory, flux linkage is a property of a two-terminal element. It is an extension rather than an equivalent of magnetic flux and is defined as a time integral [citation needed] where is the voltage across the device, or the potential difference between the two terminals. This definition can also be written in differential form as a rate.

  3. Weber (unit) - Wikipedia

    en.wikipedia.org/wiki/Weber_(unit)

    1 × 108 Mx. In physics, the weber (/ ˈveɪb -, ˈwɛb.ər / VAY-, WEH-bər; [1][2] symbol: Wb) is the unit of magnetic flux in the International System of Units (SI). The unit is derived (through Faraday's law of induction) from the relationship 1 Wb = 1 V⋅s (volt-second). A magnetic flux density of 1 Wb/m 2 (one weber per square metre) is ...

  4. Continuity test - Wikipedia

    en.wikipedia.org/wiki/Continuity_test

    Continuity test. In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.

  5. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    Analog multimeter. Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [ 1 ] is a measuring instrument that can measure multiple electrical properties. [ 2 ][ 3 ] A typical multimeter can measure voltage, resistance, and current, [ 4 ] in which case can be used as a voltmeter, ohmmeter, and ammeter.

  6. Two-tone testing - Wikipedia

    en.wikipedia.org/wiki/Two-tone_testing

    A spectrum analyser – typically used as the measuring instrument in two-tone testing. Two-tone testing is a means of testing electronic components and systems, particularly radio systems, for intermodulation distortion. It consists of simultaneously injecting two sinusoidal signals of different frequencies (tones) into the component or system.

  7. Magnetic reluctance - Wikipedia

    en.wikipedia.org/wiki/Magnetic_reluctance

    Magnetic reluctance in a magnetic circuit is analogous to electrical resistance in an electrical circuit in that resistance is a measure of the opposition to the electric current. The definition of magnetic reluctance is analogous to Ohm's law in this respect. However, magnetic flux passing through a reluctance does not give rise to dissipation ...

  8. Weber electrodynamics - Wikipedia

    en.wikipedia.org/wiki/Weber_electrodynamics

    t. e. Weber electrodynamics is a theory of electromagnetism that preceded Maxwell electrodynamics and was replaced by it by the end of the 19th century. [1] Weber electrodynamics is mainly based on the contributions of André-Marie Ampère, Carl Friedrich Gauss and Wilhelm Eduard Weber. In this theory, Coulomb's law becomes velocity and ...

  9. Henry (unit) - Wikipedia

    en.wikipedia.org/wiki/Henry_(unit)

    The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...
