Question

If the potential difference across 8 ohm resistor is 48 volt then potential difference between the terminals A and B is

Answer 1

overall resistance = 3+20/2+(24*8/24+8)+1
                             =20ohm
V across 8 ohm resister = 48v R=8ohm so I=V/I=6 A
Now R=20ohm I=6A
so V=RI
V=20*6
V=120VOLT
