S[\overline{P_M}]=\sqrt{{\overline{U}}^2 \cdot S^2[\overline{I}] + {\overline{I}}^2 \cdot S^2[\overline{U}]} = \sqrt{7.891875^2 \cdot {(1.21539 \cdot 10^{-9})}^2 + 0.002089375^2 \cdot {0.00494352}^2} = \sqrt{1.0668558757028556 \cdot 10^{-10}} = 0.000010328872

sqrt((7.891875^2) * (1.21539*10^-9)^2 + (0.002089375^2) * (0.00494352^2))




f_{эф} = (n+1) \cdot \frac{{(\overline{U}^2 \cdot S^2[\overline{I}] + \overline{I}^2 \cdot S^2[\overline{U}])}^2}{\overline{U}^4 \cdot S^4[\overline{I}] + \overline{I}^4 \cdot S^4[\overline{U}]} = (16+1) \cdot \frac{({7.891875}^2 \cdot {(1.21539\cdot 10^{-9})}^2 + {0.002089375}^2 \cdot {0.00494352}^2)^2}{{7.891875}^4 \cdot {(1.21539\cdot 10^{-9})}^4 + {0.002089375}^4 \cdot 0.00494352{}^4} - 2 = 15.000029320086769 \approx 15
