  1. V1 V3 V2 2.Vypočtu odpor Ra 3.Vypočtu Rb 5.Vypočtu Rcelko Rcelko = Ra+Rb+Rc Rcelko = 21+12+8 Rcelko = 41 1.Sečtu R1 a R2 R12=R1+R2 R12=10+20 R12=30  4.Vypočtu Rc R1 = 10  R2 = 20  R 3 =70  R 4 = 30 R 5 = 20  R 6 = 40  R 7 = 10  Ucelk = 230 V 6. Vypočtu celkový proud 8.Vypočtu napětí na II.uzlu U2 = Icelk ×Ra U2 = 5.61A×12 U2 = 67.32V Úkol zní: Vypočti proudy, které prochází jednotlivými rezistory (odpory) a napětí na voltmetrech V1-V3. 7.Vypočtu napětí na I.uzlu U1 = Icelk ×Ra U1 = 5.61A×21 U1 = 117,8V 9.Vypočtu napětí na III.uzlu U3 = Icelk ×Ra U3 = 5.61A×8 U3 = 44,88 V

  2. Brnkačka ne? U1 117,8V U267.32V U3 44,88V R1 = 10  R2 = 20  R 3 =70  R 4 = 30 R 5 = 20  R 6 = 40  R 7 = 10  Ucelk = 230 V IR12 R12=30  IR3 Icelk – 5.61 A 11.Vypočtu proudy na II.uzlu 12.Vypočtu proudy na III.uzlu 10.Vypočtu proudy na I.uzlu

  3. U = 10 V R1 = 3  R2 = 5  R3 = 15  Jaké proudy protékají odpory R1, R2 a R3? (2 body) Jaký je výsledný odpor sítě ? (1 body) 3 R 5 Taky brnkačka ne?
