Alternating Current NEET Notes : Alternating Current (AC) is an important topic in Physics that deals with the flow of electric charge in a cyclic manner. In the NEET exam , understanding AC is crucial as it frequently appears in the Physics section, especially in questions related to circuits, electrical devices, and energy transfer. This chapter helps students understand how AC differs from direct current (DC) and its applications in daily life, like in household electricity supply.

Alternating Current NEET Notes Overview
Alternating Current is a type of electrical current that reverses direction periodically. This is different from Direct Current (DC), where the electric charge flows in one direction only. AC is widely used for power transmission across long distances, as it is easier to step up or step down voltages. This chapter focuses on key concepts like alternating voltage, frequency, impedance, and power in AC circuits. Knowing these concepts is important for solving problems in the NEET exam.
