Gemischte Schaltung

1. Gesamtwiderstand mit Zwischenschritten

$R_{23} = \frac{1}{\frac{1}{R _{2}} + \frac{1}{R _{3}}} = 5 k \ohm$ $R_{123} = R_{1} + R_{23} = 10 k \ohm$ $R_{1234} = \frac{1}{\frac{1}{R _{4}} + \frac{1}{R _{123}}} = 5 k \ohm$ $R_{g es} = R_{12345} = R_{5} + R_{1234} = 5 k \ohm$

2. Gesamtstrom

$I_{g es} = U_{g es} / R_{g es} = 0, 0008 A = 0, 8 m A$

3. Rest berechnen

Spannungen

$U_{5} = I_{g es} * R_{5} = 16 V$

$U_{4} = I_{g es} * R_{1234} = 4 V$

$U_{1} = I_{123} * R_{1} = 2 V$

$U_{2} = U_{4} - U_{1} = 2 V$

Ströme

$I_{4} = U_{4} / R_{4} = 0, 0008 A = 0, 8 m A$

$I_{123} = I_{g es} - I_{4}$ = $0, 4 m A$

$I_{2} = U_{2} / R_{2} = 0, 2 m A$
