- 3. The Greek symbol Omega Ω
- 4. cell A type of electric battery, commonly used for portable electrical devices. Dry cells use an electrolyte in the form of a paste, and are thus less susceptible to leakage
- 7. A form of energy resulting from the existence of charged particles (such as electrons) either as static or as a current
- 10. A two-terminal electronic component that conducts current primarily in one direction; it has low resistance in one direction, and high resistance in the other
- 12. The unit of Voltage
- 15. Unit of Energy
- 16. A device that converts motive power into electric power for use in an external circuit
- 19. The specific amount of electricity available in a circuit. The voltage is the difference in electric potential between two points
- 20. cell A device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions
- 24. cell An electrical device that converts the energy of light directly into electricity by the photovoltaic effect
- 26. circuit A circuit that has only one path through which current can flow
- 27. A machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid
- 29. Energy Energy from a source that is not depleted when used
- 30. The unit of electrical Resistance
- 31. The unit of Power
- 33. Useful power output divided by the total electrical power consumed, typically denoted by the Greek small letter eta
- 34. A rotating machine that transforms electrical energy into mechanical energy
- 35. circuit A circuit that comprises of branches so that the current divides and only part of it flows through any branch
- 38. A unit of energy equal to one kilowatt of power sustained for one hour and is commonly used as a measure of electrical energy. One kilowatt-hour is equal to 3600 kilojoules
Down
- 1. A device contained within an electric circuit

- 13. Relating to production of electricity by waterpower constructed a hydroelectric power plant at the dam site
- 14. Energy A natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption
- 17. The seventh Greek letter used as the symbol for Electrical Efficiency (H)
- 18. The unit of Current
- 21. The rate, per unit time, at which electrical energy is transferred by an electric circuit
- 22. A flow of electrically charged particles in a circuit
- 23. A safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe level
- 25. An instrument designed to measure electric voltage
- 27. An electrical connector is a device used to join electrical conductors
- 28. A container consisting of one or more electrical cells, in which chemical energy is changed into electricity and used as a source of power
- 32. rain A form of precipitation that is unusually acidic
- 36. An instrument designed to measure electric current
- 37. A measure of the opposition to current flow in an electrical circuit
