Answer 1

SOLUCIÓN :

1) Ra = 500 ohm + 3 ohm = 503 ohm

   1/Rb = 1/ 2000 ohm + 1/ 503 ohm → Rb = 401.91 ohm

   Rc = 1000 ohm + 401.91 ohm = 1401.91 ohms .

   1/ Rd = 1/2000 ohm + 1/1401.91 ohm →  Rd= 824.18 ohm .

    Re = 1000 ohm + 824.18 ohm = 1824.18 ohms

    1/Rf = 1/ 1824.18  ohms + 1 / 2000 ohms →  Rf= 954.024 ohm

    Rt= 2000 ohm + 954.024 ohm = 2954.024 ohms . resistencia equivalente .

      Vt = It * Rt  

      It= Vt/Rt= 72 voltios / 2954.024 ohms = 0.02437 amp.

2)    1/R5,6 = 1/ 250 ohm + 1/100 ohm

      R5,6 = 500 /7 ohm

     R2,3 = R2 +R3 = 1050 ohm + 1050 ohm = 2100 ohms .

     1/Ra = 1/ ( 500/7 ohm ) + 1/ 2100 ohm

      Ra = 2625/38 ohms .

     Rt = Ra  + R1 = 2625/38 ohm + 150 ohm

     Rt= 8325/38 ohms = 219.078 ohms

    It= Vt/ Rt = 12 v/ 219.078 ohms = 0.0547 ohms .
