Electricity

5. Current – The rate of flow of electric charge through a conductor, measured in amperes.
7. Power – The rate at which electrical energy is transferred or converted, measured in watts (P = VI).
8. – The SI unit of electric potential difference, equal to one joule per coulomb.
10. Current – Electric current that periodically reverses direction.
12. – A fundamental property of matter (measured in coulombs) that causes it to experience a force in an electric field.
14. – The work done per unit charge in moving a charge between two points in an electric field; equivalent to potential difference.
16. – A material that allows electric charges to flow easily due to its low resistance.
17. – The SI unit of electrical resistance, equal to one volt per ampere.
19. Diagram – A graphical representation of an electrical circuit using standardized symbols.
20. Circuit – A circuit in which components are connected across common nodes, providing multiple paths for current.

1. Force – The force between two charged objects, described by Coulomb’s law.
2. Current – Electric current that flows in one constant direction.
3. – A closed path through which electric charges flow.
4. Difference – The difference in electrical potential between two points, also called voltage.
6. Potential – The electric potential energy per unit charge at a point in a field, measured in volts.
9. – A device that stores electric charge and energy in an electric field, consisting of two conductors separated by an insulator.
11. Circuit – A circuit in which components are connected end‑to‑end so that current flows through each in turn.
13. Resistance – The property of a material that opposes the flow of electric current, measured in ohms.
15. Law – The relationship V = IR, stating that the voltage across a conductor is proportional to the current through it.
18. – The SI unit of electric current, equal to one coulomb per second.
