Kirchhoffs current law (KCL) states:

A Voltage around a loop = 0

B The algebraic sum of currents entering and leaving a node equals zero

C Power is constant

D Resistance is constant

✓ Correct Answer: Option B

KCL: charge conservation. ΣI_in = ΣI_out at any junction. Fundamental for node analysis.

💡 Why is B) the correct answer?
