What is the potential difference between A and B in the above circuit element?
- A 40 V
- B 35 V
- C 25 V
- D 55 V
Answer & Solution
Correct Answer
(B) 35 V
Step-by-step Solution
Detailed explanation
The circuit consists of a series combination of resistors and voltage sources. The current \(I = 1\text{ A}\) flows from A to B. Applying Kirchhoff's Voltage Law (KVL) starting from point A to point B: \(V_A - I(18) - 10 - I(3) + 5 - I(9) = V_B\) Substituting the value of…
