Define electric charge density.
Electric charge density is a measure of the amount of electric charge per unit volume at a given point in space. It is calculated as the ratio of charge to volume and is measured in coulombs per cubic meter (C/m^3).

See lessWhat is the role of an electrical conductor?
An electrical conductor is a material that allows electric current to flow through it easily. It is used to carry electrical signals or power between components in an electrical circuit and is typically made of metals such as copper or aluminum.

See lessDefine electrical grounding.
Electrical grounding is the process of connecting electrical equipment or systems to the Earth or to a conductive structure to ensure safety and proper functioning. It provides a path for excess electrical current to flow safely to the ground, preventing electrical shocks and equipment damage.

See lessWhat is the function of an electrical switch?
An electrical switch is a device used to interrupt or divert the flow of electric current in a circuit. It is commonly used to control the operation of electrical devices or circuits, allowing them to be turned on or off as needed.

See lessDefine electric field lines.
Electric field lines are imaginary lines that represent the direction and magnitude of the electric field at different points in space. They always point away from positive charges and toward negative charges and are used to visualize electric field patterns.

See lessWhat is the difference between an insulator and a semiconductor?
An insulator is a material that inhibits the flow of electrical current, while a semiconductor is a material whose conductivity lies between that of a conductor and an insulator. Semiconductors are commonly used in electronic devices such as diodes and transistors.
