Can you explain the difference between AC (Alternating Current) and DC (Direct Current)?

Alternating Current (AC) and Direct Current (DC) are two fundamental types of electrical current, each with distinct characteristics and applications.

AC (Alternating Current)

In AC, the flow of electric charge periodically reverses direction. This type of current is commonly used in households and industries because it can be easily transformed to different voltage levels using transformers, making it efficient for transmitting power over long distances.

AC is typically generated by power stations and distributed through the grid, powering appliances, lighting, and other electrical systems in homes and businesses.

The voltage of AC can vary (e.g., 120V, 230V) depending on the region and application.

Explain the working principle of a transformer and its key components.

A transformer operates on the principle of electromagnetic induction to transfer electrical energy between two or more circuits. It consists of two main components: the primary coil and the secondary coil, both wound around a common core.

When alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil. The voltage induced in the secondary coil depends on the turn ratio of the coils.

Transformers are used to step up or step down voltage levels in power systems, ensuring efficient power transmission and distribution.

The core, usually made of laminated iron, enhances efficiency by minimizing energy losses.
