WebI, equals, start fraction, delta, q, divided by, delta, t, end fraction. is change in time. Current is the change in charge over the change in time. R, equals, start fraction, rho, l, divided by, A, end fraction. Resistance is proportional to resistivity and length, and inversely proportional to cross sectional area. WebHi Cuiping, As far as I understand it, the bits before the = sign are just giving that line a name. So in this case it's saying "for my next trick I will perform an action called Replaced OTH".After the = sign, you get the name of the function that's being applied in this line, and then the first bit in the bracket is the name of the previous line. I presume this is so that it … WebPower Formulas in Single Phase AC Circuits P = V x I x Cos Ф P = I2 x R x Cos Ф P = V2 / R (Cos Ф) Power Formulas in Three Phase AC Circuits P = √3 x VL x IL x Cos Ф P = 3 x VPh x IPh x Cos Ф P = 3 x I2 x R x Cos Ф P … helsel jepperson electrical inc
