-------------------------------------- Electrical calculations i = 1.00000e+01 rp = 5.00000e+00 rres = 1.00000e+00 / (1.00000e+00 / rp + 1.00000e+00 / rp) = 2.50000e+00 u = i * rres = 2.50000e+01 -------------------------------------- Power from current and resistance power = i ^ 2.00000e+00 * rres = 2.50000e+02 -------------------------------------- Power from voltage and resistance power2 = u ^ 2.00000e+00 / rres = 2.50000e+02 --------------------------------------
