In the above question, if the internal resistance of the battery is 1 ohm, then what is the reading of ammeter
A) 5/3 A
B) 40/29 A
C) 10/9 A
D) 1 A
Correct Answer:
B
Solution :
Applying Kirchhoff law in the first mesh \[10=5{{i}_{1}}+i\] .....(i) Applying in the second mesh \[5{{i}_{1}}=4i-4{{i}_{1}}\] ......(ii) Solving equation (i) and (ii), we get \[{{i}_{1}}=\frac{40}{29}\,A\]
