Find the value of current I in the circuit given below:

Resistors across AC and DE are in parallel i.e. RAC and RDE are in parallel.

So






Now R’p and RBC are I series.


R’s = R’p + RBC


R’s = 15 + 15 = 30Ω.


Again, RAB and R’s are in parallel.





R’’p =


Equivalent resistance of the above circuit is 10Ω.


Now, current flowing through the circuit is


I =


The value of current is 0.3A
