Solution
Correct Answer:
Zero
Kirchhoff's Voltage Law (KVL), based on the Conservation of Energy, states that the algebraic sum of all potential differences (EMFs and IR drops) around any closed loop in a circuit must be zero. ∑ΔV=0
- This means the energy gained per unit charge from sources equals the energy dissipated across resistors.
This medium difficulty physics question is from the chapter current electricity, covering the topic of kirchhoff's voltage law. It appeared in the 2025 exam.
