Phasor analysis is a mathematical technique used to simplify the analysis of linear electrical circuits with sinusoidal sources by converting time-domain sinusoidal functions into frequency-domain phasors. This method allows for the straightforward application of Ohm's and Kirchhoff's laws to solve complex circuit problems involving alternating current (AC).

Ohm's Law is a fundamental principle in electronics and electrical engineering that states the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. This relationship is mathematically expressed as V = IR, where V is voltage, I is current, and R is resistance.

Kirchhoff's Laws consist of two fundamental rules for analyzing electrical circuits: Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL), which help determine the current and voltage distribution in complex networks. These laws are based on the principles of conservation of charge and energy, making them essential tools for circuit analysis in electrical engineering.

Alternating current (AC) is an electric current that periodically reverses direction, unlike direct current (DC) which flows only in one direction. AC is the form of electricity delivered to homes and businesses and is used for powering appliances and lighting due to its efficient transmission over long distances.
