Answer:

Explanation:

The given circuit is forming a balanced wheat-stone bridge.

The equivalent resistance of the circuit will be given by:

10 Ω &2 Ω are in series and 25 Ω & 5 Ω are in series.

Equivalent for 10 Ω &2 Ω

R  

e1

​  

=12 Ω

Equivalent for 25 Ω & 5 Ω

R  

e2

​  

=30 Ω

Total Equivalent R  

e

​  

 

R  

e

​

​  

=  

12

​  

+  

30

​  

 

R  

e

​  

=

60

​  

 

Also:

i

​  

R  

e1

​  

=i

​  

R  

e2

​  

 

i

​  

 

i

​  

 

​  

=

5

​  

 

Thus, the current will be divided in the circuit in ratio of5:2

Thus, the current in R  

e1

​  

 will be

i  

1

​  

=  

7

1.4×5

​  

=1 A

Thus the current in 2 ohm resistance nwill be 1 A
