  1. 2. also known as potential difference, electric pressure, or electric tension is the difference in electric potential between two points. In a static electric field, it corresponds to the work
  2. 4. the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
  3. 6. resistance of a conductor of unit cross-sectional area and unit length
  4. 7. a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.
  5. 8. CircuitComponents are connected alongside one another, forming extra loops
  6. 9. In science, a conductor is a material that permits a flow of energy. A material that allows the flow of charged particles is an electrical conductor. A material that enables the transfer of thermal energy is a thermal conductor or heat conductor.
  7. 11. a complete circular path that electricity flows through
  8. 12. An electromechanical device with movable electrical contacts that can connect or disconnect external circuits.
  9. 13. DiagramA circuit diagram is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnecti
  10. 14. the current in which one coulomb of charge travels across a given point in 1 second.
  11. 16. allow electrons to flow freely, making them useful for carrying electric current.
  12. 18. One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.

  1. 1. a device that stores chemical energy, and converts it to electricity.
  2. 3. with stationary or moving electric charges
  3. 5. the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.
  4. 10. electrical resistance of a conductor of unit cross-sectional area and unit length
  5. 15. In the context of chemistry and physics, charge usually refers to electric charge, which is a conserved property of certain subatomic particles that determines their electromagnetic interaction. Charge is a physical property that causes matter to experience a force within an electromagnetic field.
  6. 17. unit of electrical resistance in the metre-kilogram-second system, named in honour of the 19th-century German physicist Georg Simon Ohm. It is equal to the resistance of a circuit in which a potential difference of one volt
  7. 19. Law Ohm’s law, description of the relationship between current, voltage, and resistance. The amount of steady current through a large number of materials is directly proportional to the potential difference, or voltage, across the materials.
