- 2. A switch responds to an external force to mechanically change an electric signal.
- 5. Circuit: series circuit, any electrically conducting pathway comprising an electric circuit along which the whole current flows through each component.
- 6. Diagram: A circuit diagram is a graphical representation of an electrical circuit.
- 9. 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.
- 10. Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
- 11. Electric circuit, path for transmitting electric current
- 14. Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
- 15. Unit of electric current
- 16. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
- 18. A conductor, or electrical conductor, is a substance or material that allows electricity to flow through it.
- 19. Circuit: parallel circuit, an electrical path that branches so that the current divides and only part of it flows through any branch.
- 20. — electricity, phenomenon associated with stationary or moving electric charges. Electric charge is a fundamental property of matter
Down
- 1. Law: Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.
- 3. Electrical resistivity is a measure of a material's property to oppose the flow of electric current.
- 4. . Current is the rate at which electrons flow past a point in a complete electrical circuit.
- 7. The ohm is a measurement of resistance between two points of a conductor when a constant potential difference of one volt (V) is applied to those points and a current of one ampere (A) is produced.
- 8. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.
- 12. An electrical cell is an "electrical power supply"
- 13. An electrical insulator is a material in which electric current does not flow freely.
- 17. Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
