Direct Current (DC): Direct current is an electric current that flows in one direction only, without changing its polarity. It is commonly used in batteries and electronic devices.
Transformer: A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It plays a crucial role in stepping up or stepping down the voltage of AC power for transmission and distribution.
Power Grid: The power grid refers to the network of power stations, transformers, and transmission lines that deliver electricity from producers to consumers. It enables efficient distribution of electrical power across large areas.
