The value of current through the 5 resistor of the given circuit is
Options
- A1 25 ~A
- B2 25 ~A
- C2 23 ~A
- D1 23 ~A
Correct answer
D. 1 23 ~A
Step-by-step solution
By KVL aligned & 4 i +8 i ₁-5=0 [In smaller loop] & 4 i ₁+4 i ₂+8 i ₁-5=0 & 12 i ₁+4 i ₂=5 ...(i) & and, 5 i ₂+3-8 i ₁=0 [In bigger loop] & 5 i ₂-8 i ₁=-3 & 5 i ₂-8 ( 5-4 i ₂ 12 )=-3 [ from ( i )] & aligned aligned & 5 i ₂- 2 3 (5-4 i ₂ )=-3 & 5 i ₂- 10 3 + 8 3 i ₂=-3 & 23 3 i ₂= 1 3 & i ₂= 1 23 Current through 5 = 1 23 ~A aligned
