Question

What is the current through the 10V battery
answer given is 4 A​

Answer 1

Answer: 10Volt battery by V= IR

the total current in the circuit is

I= V/R=10/2=5A

i hope this will help you

Answer 2

v=ir

i=v/r ,current through 10v battery is equal to current through 4ohm and 2ohm resistors

current through 4ohm =10v-6v/4=1A

current through 2ohm=10v-4v/2=3A

hence current through 10v =3A+1A=4A
