Lösning 4.4:8
FörberedandeFysik
\displaystyle P = 800 W \displaystyle U = 115 V \displaystyle P = U\cdot I \Rightarrow 800 = 115\cdot I
\displaystyle I=6,96 A \displaystyle \omega = 314 rad/s
\displaystyle 230 = \sqrt{(115)^2 + (U_c)^2} \Rightarrow U_c = 199,2 V \displaystyle U_c = I\cdot 1/ \omega C
\displaystyle C = 1,1 \cdot 10^{-4} F(110\mu F)
