     • The transformer equation\u00a0E = 4.44(f)(B)(N)(a)<\/code><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

       Where,<\/p>\n

       \n
       • \n
         \n
         • E is the voltage in the winding either primary or secondary,<\/li>\n
         • f is the frequency,<\/li>\n
         • B is the flux density in the core,<\/li>\n
         • N are the number of turns on the winding, and<\/li>\n
         • a is the cross area of the core.<\/li>\n
         • At higher frequencies the number of winding turns N is reduced.<\/li>\n<\/ul>\n<\/li>\n
         • This formula follows from the Faraday formula, E = N d\u03b8\/dt and \u03b8 = B(a).<\/li>\n
         • This formula is switching power supplies use a much higher frequency (thousands of hertz) than 60 hertz, they use smaller transformers that don’t need as much wire as transformers operating at 60 hertz.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
