Electrical

Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.

Electric Charge

Electric charge is a fundamental property of matter. There are two types of electric charge: positive and negative. Like charges repel each other, while opposite charges attract each other.

Electric Current

Electric current is the flow of electric charge in a conductor. It is measured in amperes (A). The flow of current is driven by the potential difference, or voltage, across the conductor.

Voltage

Voltage is the difference in electric potential between two points. It is measured in volts (V). Voltage is what causes electric charge to flow through a circuit.

Resistance

Resistance is the opposition to the flow of electric current. It is measured in ohms (Ω). The relationship between voltage, current, and resistance is described by Ohm's law: V = I * R, where V is voltage, I is current, and R is resistance.

Electric Circuits

An electric circuit is a closed loop through which an electric current can flow. It typically consists of a voltage source, conductors, and loads (such as light bulbs or motors). Circuits can be series, parallel, or a combination of both.

Magnetism and Electricity

Electricity and magnetism are closely related. Moving electric charges create magnetic fields, and changing magnetic fields can induce electric currents. This relationship is described by Maxwell's equations.
