This paper discusses two of the most common techniques for circuit analysis: Kirchhoff's current law (KCL) and phasor analysis. KCL is a basic law of circuit analysis that states that the sum of the currents entering a node is equal to the sum of the currents leaving the node. Phasor analysis is a technique for representing sinusoidal voltages and currents as rotating vectors. It can be used to simplify complex circuits and to solve circuit problems that would be difficult to solve using other methods.

Keywords- Circuit analysis, Kirchhoff's current law (KCL), Phasor analysis, Sinusoidal voltages and currents, Rotating vectors, Complex circuits
