Kirchhoff's Current Law
Kirchhoff's current law states algebraic sum of currents at junction is:
Select the correct option:
Solution
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.
