Solution
Correct Answer:
Zero
Kirchhoff's Current Law (KCL), based on the Conservation of Charge, states that at any junction in an electrical circuit, the sum of currents entering is exactly equal to the sum of currents leaving. ∑I=0
- Incoming currents are taken as positive, outgoing as negative.
- Charge cannot accumulate at a junction point.
This medium difficulty physics question is from the chapter current electricity, covering the topic of kirchhoff's current law. It appeared in the 2025 exam.
