Kirchhoff's current law is applicable to which type of circuits:
Correct answer: C. Any of these
- A. Series
- B. Parallel
- C. Any of these
- D. None of these
Explanation
Kirchhoff's current law states that the total current entering a junction must equal the total current leaving that junction. This law is applicable to all types of circuits, whether they are series, parallel, or a combination of both. In a series circuit, the current is the same at all points, and in a parallel circuit, it divides among the branches, but the law still holds true in both cases. Therefore, the correct answer is 'Any of these.' The other options are incorrect as they either limit the applicability of the law or incorrectly suggest it doesn't apply at all.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
