Question

Are Kirchhoff’s laws applicable to both AC and DC currents?

Short/Brief Note
Advertisements

Solution

Yes, Kirchoff's law states that the algebraic sum of the flow of current into and out of a node must be equal. This is true for all DC circuits, and for AC circuits at frequencies where the wavelengths of electromagnetic radiation are very large compared to the circuits the law is valid.
