Electricity is measured in units of energy called joules. Power companies measure electricity in units of kilowatt-hours (kWh) for billing purposes.

Electric and magnetic fields are forces that can affect objects and materials. They are created by charged particles and moving electrons.

An inductor is a passive electronic component that stores energy in a magnetic field. It is used in circuits to block AC current and reduce noise.

A capacitor is a passive electronic component that stores electrical charge and releases it when needed in a circuit. It is commonly used in power supplies, filters, and timing circuits.

Electrical symbols are graphical symbols used to represent electrical and electronic devices, parts, and functions in circuit diagrams.

Circuit breakers and fuses are essential components of electrical systems. They work by interrupting the flow of electricity when there is a problem.

Electrical switches come in a variety of types, including toggle, rocker, push-button, and dimmer switches. Each has its unique features and uses.

Electrical grounding serves as a vital safety measure in any electrical system. It prevents electrocution and protects appliances from damage caused by power surges.

Static electricity is the buildup of electric charge on a surface due to the transfer of electrons. It can be seen in everyday life and has practical applications in technology.

A transformer is an electrical device that transfers energy between two circuits through electromagnetic induction. It works on the principle of mutual induction.
