Determine the current in the following circuit
A
1 A
B
2.5 A
C
0.4 A
D
3 A
Answer
1 A
Explanation
Solution
Applying KVL in the given circuit we get
−2i+10−5−3i=0 ⇒ 
Second method : Similar plates of the two batteries are connected together, so the net emf = 10 – 5 = 5V
Total resistance in the circuit = 2 + 3 = 5Ω
∴
