2. Skin effect - Wikipedia

   en.wikipedia.org/wiki/Skin_effect

   Skin effect reduces the effective cross-section of the conductor and thus increases its effective resistance. At 60 Hz in copper, skin depth is about 8.5 mm. At high frequencies, skin depth becomes much smaller. Increased AC resistance caused by skin effect can be mitigated by using a specialized multistrand wire called litz wire. Because the ...

3. Electrical resistivity and conductivity - Wikipedia

   en.wikipedia.org/wiki/Electrical_resistivity_and...

   The SI unit of electrical resistivity is the ohm - metre (Ω⋅m). [1][2][3] For example, if a 1 m3 solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m. Electrical conductivity (or specific conductance) is the reciprocal of ...

4. Electrical resistance and conductance - Wikipedia

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

   The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction. The SI unit of electrical resistance is the ohm (Ω ...

5. Litz wire - Wikipedia

   en.wikipedia.org/wiki/Litz_wire

   Litz wire consists of multiple strands insulated electrically from each other. Ordinarily the strands are twisted or woven, but no twisting is shown in this diagram. Litz wire is a particular type of multistrand wire or cable used in electronics to carry alternating current (AC) at radio frequencies. The wire is designed to reduce the skin ...

6. Electrical conductor - Wikipedia

   en.wikipedia.org/wiki/Electrical_conductor

   For a given material, the resistance is inversely proportional to the cross-sectional area. [1] For example, a thick copper wire has lower resistance than an otherwise-identical thin copper wire. Also, for a given material, the resistance is proportional to the length; for example, a long copper wire has higher resistance than an otherwise ...

7. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric ...
