1. Wyznaczanie G_i0.

$$G_{i0} = \frac{\frac{U_{\text{wy}}}{R_{L1}}}{\frac{U_{\text{we}}}{r_{\text{we}}}} = \frac{\frac{160*10^{- 3}}{0,85*10^{3}}}{\frac{4,10*10^{- 3}}{5,95*10^{3}}} = 273,17\lbrack\frac{A}{A}\rbrack$$

$$G_{i0} = \frac{\frac{U_{\text{wy}}}{R_{L2}}}{\frac{U_{\text{we}}}{r_{\text{we}}}} = \frac{\frac{650*10^{- 3}}{3,59*10^{3}}}{\frac{4,10*10^{- 3}}{5,95*10^{3}}} = 262,76\lbrack\frac{A}{A}\rbrack$$

1. Wyznaczanie G_u0s.

$$G_{u0s} = \frac{U_{\text{wy}}}{E_{g}} = \frac{160*10^{- 3}}{5*10^{- 3}} = 32\lbrack\frac{V}{V}\rbrack$$

$$G_{u0s} = \frac{650*10^{- 3}}{5*10^{- 3}} = 130\lbrack\frac{V}{V}\rbrack$$

1. Wyznaczanie G_i0s.

$$G_{i0s} = G_{u0s}*\frac{R_{g}}{R_{L1}} = 32*\frac{1*10^{3}}{0,85*10^{3}} = 37,65\lbrack\frac{A}{A}\rbrack$$

$$G_{i0s} = G_{u0s}*\frac{R_{g}}{R_{L2}} = 130*\frac{1*10^{3}}{3,59*10^{3}} = 36,21\lbrack\frac{A}{A}\rbrack$$
