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
