  1. 5. the rate at which electrical energy is transferred, consumed, or converted into other forms (like heat or light) within a circuit.
  2. 7. the difference in electrical potential energy per unit charge between two points in an electrical circuit.
  3. 8. the SI base unit of electric current, defined as the flow of one coulomb(C) of electric charge per second(s) past a point. 1A= 1C/s
  4. 10. a device that stores electrical energy in the electric field between two parallel sheets.
  5. 11. a noncontact interaction between two objects having electric charge.
  6. 15. a fundamental physical property of subatomic particles (like protons and electrons) that causes them to experience a force when placed in an electromagnetic field.
  7. 17. a closed, continuous loop of conductive material that allows charge carriers (electrons) to flow, driven by a potential difference.
  8. 18. the electric potential difference that produces electric current between two points in a circuit.
  9. 19. the measure of opposition to current flow in an electrical circuit, determined by how difficult it is for electrons to pass through a material.

  1. 1. the proportional relation of current and field; E = pl and V = IR.
  2. 2. an electrical circuit where components are connected across the same two nodes, creating multiple, independent paths for current to flow.
  3. 3. the SI derived unit of electrical potential difference, electromotive force (EMF), or voltage.
  4. 4. an electrical circuit where all components are connected end-to-end in a single path, meaning the same current flows through every component.
  5. 6. the rate at which electric charge passes through an area of wire.
  6. 8. an electric current that periodically reverses direction and changes magnitude continuously with time.
  7. 9. a two-dimensional drawing that uses standard symbols rather than realistic pictures to show how components in a system—like an electrical circuit—are connected.
  8. 12. a material, such as a metal, that allows electric charges to easily move through it.
  9. 13. the International System of Units (SI) derived unit for electrical resistance, measuring how strongly a material opposes the flow of electric current.
  10. 14. the unidirectional flow of electric charge, meaning electrons move in only one direction within a conductor.
  11. 16. the amount of electric potential energy(U) per unit charge(q) at a specific point in an electric field.
