What is the role of a capacitor in an electrical circuit?
A capacitor is an electronic component used to store and release electrical energy. It consists of two conductive plates separated by an insulating material (dielectric). Capacitors are commonly used in circuits for energy storage, filtering, and timing.

See lessWhat is the purpose of a circuit breaker in an electrical system?
A circuit breaker is a safety device that automatically interrupts the flow of electric current in a circuit when abnormal conditions, such as overcurrents or short circuits, are detected. It protects electrical circuits and devices from damage due to excessive currents.

See lessDefine specific resistance (or resistivity).
Specific resistance, also known as resistivity, is a measure of a material's resistance to the flow of electric current. It is intrinsic to the material and is measured in ohm-meters (Ω⋅m).

See lessWhat is an electric field line?
An electric field line is an imaginary line that represents the direction and magnitude of the electric field at different points in space. Electric field lines always point away from positive charges and toward negative charges.
