There are two types of electricity - static and current. The current electricity is divided into Alternating Current (AC) and Direct Current (DC). Based on the production methods, electricity is divided into - heat, chemical, pressure, light and magnetism.

There are four types of power supply - switch-mode power supplies, linear power supplies, linear power supplies, and programmable power supplies

According to this law, at any point, magnetic field due to a tiny current element is directly proportional to the current element length.

Tesla (T) is the SI unit of magnetic field. Tesla is named after Nikola Tesla.

The different types of magnetism are - Diamagnetism, Paramagnetism, and Ferromagnetism.

The examples of the probability include - flipping a coin, rolling a die, drawing a card from a deck, and picking a ball from a bag.
