Learn new vocab by taking this fun trivia quiz! The lowercase letter φ (or often its variant, ϕ) is often used to represent the following: The uppercase letter Φ is used as a symbol for: The diameter symbol in engineering, ⌀, is often erroneously referred to as "phi", and the diameter symbol is sometimes erroneously typeset as Φ. The rotation of a three-phase motor may be reversed by reversing, and Charging Benches any two of the cables.
{\displaystyle \Phi \,\!} During the later part of Classical Antiquity, in Koine Greek (c. 4th century BC to 4th century AD), its pronunciation shifted to that of a voiceless bilabial fricative ([ɸ]), and by the Byzantine Greek period (c. 4th century AD to 15th century AD) it developed its modern pronunciation as a voiceless labiodental fricative ([f]). 4.

It typically appears in a form adapted to a Latin typographic environment, with a more upright shape than normal Greek letters and with serifs at the top and bottom. {\displaystyle \varphi \,\!} Three-phase winding - Star Changer, general symbol Converter, general symbol Notes: (1) If the direction of change is not obvious, it may be indicated by an arrowhead on the outline of the symbol.

I am a mechanical engineering student by major, but I am taking mechatronics and robotics courses so I'm about the most electrical-heavy ME you'd meet. This also applies to the "Didot" (or "apla") typefaces employed in most Greek book printing ( ), as well as the "Neohellenic" typeface often used for ancient texts ( ). For use as a phonetic symbol in IPA, Unicode has a separate code point U+0278, LATIN SMALL LETTER PHI, because only the stroked glyph is considered correct in this use. The result produced by three such coils is called a three-phase current. Three-phase definition, of or relating to a circuit, system, or device that is energized by three electromotive forces that differ in phase by one third of a cycle or 120°. It may be that phi originated as the letter qoppa, and initially represented the sound /kʷʰ/ before shifting to Classical Greek [pʰ].
