Any machine powered by electricity or for protection. _______3. A small bag or box equipped with hand tools. _______4. Connecting two lengths of conductor, to join ropes or wires by weaving or twisting them together. _______5. Removing the insulation of connecting wires. _______6. A pocket-sized tool used to test the presence of current in a line wire or circuit _______7. Used to measure the current flowing in a conductor. It is clamped or hanged in a conductor. _______8. It is an electrical device that measures voltage, current, and resistance. _______9. It is an electronic device that measures resistance in an electronic component or circuit. _______10. An instrument used for measuring the potential difference or voltage between two points in an electrical circuit. _______11. Is an instrument used to measure the flow of electric current in a circuit. _______12. This used for removing burrs in conduits. _______13. This is a special flexible steel wire used for pulling the conductors in conduits. _______14. A blank punched out of a piece of sheet metal. Conduit- a pipe or tube _______15. This used for removing burrs of newly cut conduits. It is available in different sizes. _______16. This is a slotted circular disk used to find the diameter or size of an electrical wire. _______17. Used to measure the length of an object in centimeters and inches. This is also used to measure heights for switches and outlets.

_______18. Used to measure length, width, and thickness of short flat objects and to draw straight lines. _______19. This is used to measure the diameter and thickness of cables, wires, or conductors. _______20. This is used to solder connecting wires _______21. This is used for removing soldered wires. _______22. Is a place where the soldering iron is placed during usage. _______23. This is a wire-like boring tool used in making initial holes for split knob screws. _______24. A small drilling machine with a chuck capacity of ¼ to 3/8 inch. It is used in making holes on metal sheets and concrete walls. _______25. A device designed to open and close a circuit by non-automatic means and to open the circuit automatically on predetermined overload of current without injury to itself when properly applied within its rating. _______26. A conducting connection whether intentional or accidental between an electrical circuit or equipment and earth, or to some conducting body which serves in place of the earth. _______27. a point on the wiring system at which current is taken to supply utilization equipment. _______28. It includes buses, with or without switches and/or automatic over current protective devices for the control of light, heat or power circuits of small individual as well as aggregate capacity. _______29. Charges can move through any of several paths. _______30. a circuit in which all parts are connected end to end to provide a single path for current. _______31. The movement of charged particles in a wire to a specific direction. The charged particles may be a positive ion or a negative ion. _______32. It is the electric pressure that causes current to flow. _______33. Is the opposition to the flow of charge. _______34. Is a welding technique in which a flux covered electrode helps create a welded joint.

STICK WELDING ADVANTAGES _______35. Works well in _____ and rainy conditions. _______36. ____________, equipment is inexpensive. _______37. No external shielding gas is required since the ____provides the protective gaseous layer – this makes stick welding cost- effective. _______38. Compared to other welding techniques, stick welding is ____severely affected by dirt, corrosion and paint – this can save pre-welding cleaning time. _______39. You can change ___ easily for various metals. _______40. You can attach the ground ____ at a considerable distance from the welding area. _______41. This kind of joint is commonly used to join two or more conductors inside the junction box. _______42. This method of wrapping is generally used on small cables because the strands are flexible, and all can be wrapped in one operation. _______43. This is a two-tap wire turned simultaneously and is used where the two-tap wire is under heavy tensile stress. _______44. This is the most widely used splice or joint in interior wiring installation to extend the length of wire from one point to another. _______45. This is used extensively for outside wiring to extend the length of wire from one end to another. _______46. This is used on large solid conductors where it is difficult to wrap the heavy tap wire around the main wire.
