Kirchhoff's current law (KCL) is a fundamental principle in electric circuits that states that the algebraic sum of currents entering and leaving a node (or junction) in an electric circuit is zero. It is based on the principle of conservation of charge, which states that the total charge entering a node must be equal to the total charge leaving the node.
KCL can be derived from the principle of conservation of charge, where any charge entering a node must eventually leave the node, resulting in the sum of currents being zero at the node.
Therefore, both the Assertion and Reason are true, and the Reason provides a correct explanation of the Assertion.

Assertion: Kirchhoffs current law (KCL) states that the algebraic sum ...
Explanation:

Assertion:
Kirchhoff's current law (KCL) states that the algebraic sum of currents entering and leaving a node in an electric circuit is zero.

Reason:
KCL is based on the principle of conservation of charge.

Explanation:
  • Assertion is true: Kirchhoff's current law (KCL) is a fundamental law in electrical engineering that states that the total current entering a node in a circuit must be equal to the total current leaving the node. This is represented mathematically as ΣI(in) = ΣI(out), where Σ represents the sum of currents entering and leaving the node.
  • Reason is true and the correct explanation of the Assertion: KCL is indeed based on the principle of conservation of charge. According to the principle of conservation of charge, charge cannot be created or destroyed in an isolated system. Therefore, the total charge entering a node in an electric circuit must be equal to the total charge leaving the node, leading to the formulation of Kirchhoff's current law.


Therefore, option 'A' is the correct choice as both the Assertion and Reason are true, and the Reason provides the correct explanation for the Assertion.
