ELECTRICITY Introduction It is a source of energy. This energy can be converted into: Sound Energy Heat Energy Light Energy Etc There are two types of electricity AC [Alternating Current] DC [Direct Current] AC are more dangerous to us because it is used for home purposes and industrial purposes. [Voltage 110V 240V for home 440V+ for industrial] DC uses less voltage when compared to AC [24V-5V for PCB and other boards] DC are present in batteries, cells , etc AC converted to DC using adapters and DC-AC using inverters. CELL A cell is a single unit that generates electrical energy through chemical reactions. It has two terminals—positive and negative—and produces a voltage that can be used to power devices. Examples include dry cells (like AA or AAA batteries) and wet cells (used in car batteries). BATTERY A battery is a collection of multiple cells connected together to provide greater voltage and capacity. It stores and supplies electrical energy to devices, and comes in differen...
