Dik : R1 = 40 ohms

         R2 = 96 ohms

         R3 = 24 ohms

        EMF = 74 volts

Dit : I Pada R3 ?

Jawab :

I3 = V/R3

    = 74/24 

    = 3.08 Ampere

I2 = V/R2

    = 74/96

    = 0,7708 Ampere

I1 = V/R1

    = 74/40 

    = 1,85 Ampere 

Rtotal = 40 + 1/96 + 1/24 = 45/96 = 0,046875 Ohms

Itotal = V/Rtotal

         = 74/0,046875

         = 157,866667 Ampere
