AnweR :
To FinD :
▪ Potential difference b/w points A and B.
ConcepT :
▪ This question is completely based on kirchhoff's second law.
▪ This is also called as loop rule.
Mathematically,
☞ Σε = Σ(IR)
CalculatioN :
✏ Case - 1) :
→ (V)A - (2×2) - 3 - (2×1) = (V)B
→ (V)A - (V)B = 4 + 3 + 2
→ (V)A - (V)B = 9volt
✏ Case - 2) :
→ (V)A - (2×2) + 3 - (2×1) = (V)B
→ (V)A - (V)B = 4 - 3 + 2
→ (V)A - (V)B = 3volt
