EIM QUIZ

Current

what flows on a wire or conductor. measured in (A)

Voltage

difference in electrical potential between two points in a circuit. It's the push or pressure behind current flow through a circuit, and is measured in (V)

Resistance

determines how much current will flow through a component. used to control voltage and current levels. measured in ohms.

Power

amount of current times the voltage level at a given point measured in wattage or watts.

Screw Drivers

made of steel hardened and tempered at the tip used to loosen or tighten screws with slotted heads. They come in various sizes and shapes.

Standard/Flat Screw Driver

The blade tip is wedge-shaped and resembles a negative (-) sign. This is used to drive screws with a single slot head.

Philips Screw Driver

Pliers

made from metal with insulators in the handle and are used for cutting, twisting, bending, holding, and gripping wires and cables.

Combination Pliers (Lineman’s Pliers)

used for gripping, holding, and cutting electrical wires and cables and even small nails. They are usually used by linemen in doing heavy tasks.

Side Cutting Pliers

used for cutting fine, medium and big wires and cables.

Long Nose Pliers

used for cutting and holding fine wires. This can reach tight space or small opening where other pliers cannot reach and also used in making terminal loops of copper wires.

Wire Stripper

used for removing insulation of medium sized wires ranging from gauge #10 to gauge #16.

Electrician’s Knife

used by linemen to remove insulation of wire and cables in low and high voltage
transmission lines.

Portable Electric Drill

small drilling machine with a chuck capacity of ¼‖ to 3/8‖. It is used in making holes on metal sheets and concrete walls.

Hacksaw

used to cut metal conduit and armored cable.

Convenience Outlet

convenient source of electrical energy for current consuming appliances. It maybe single, duplex, triplex or multiplex and could be surface type or flush type.

Surface Type-Duplex

what kind of outlet is this?

Flush Type-Duplex

what kind of outlet is this?

Male Plug

a device inserted to a convenience outlet to conduct electric current. A flat cord is attached to it on one end and the other end is connected to a current consuming instrument or appliance.

Lamp Holders

devices that hold and protect the lamp. These come in many designs and sizes. They are classified as flush, hanging (weather proof/chain) and surface types.

Lamp Sockets/Receptacles

what are lamp holders also called?

Switch

a device that connects and disconnects the flow of electric current in a circuit. There are many shapes, designs, and types and they are classified as hanging, flush, and surface types.

Surface Type Switch

what kind of switch is this?

Flush Type Switch

what kind of switch is this?

Fuse

circuit protective device that automatically blows and cut the current when and over load or short circuit happens.

Circuit Breaker

protective device used to automatically blows and cuts the current when trouble in the circuit such as short circuit or overload occurs.

Junction Box

octagonal shaped electrical material where the connections or splices of wires are being done. It is also where the flush type lamp holder is attached. This could be made of metal or plastic (PVC) Polyvinylchloride.

Utility Box

rectangular shaped metallic or plastic (PVC) material in which flush type convenience outlet and switch are attached.

Flat Cord

duplex stranded wire used for temporary wiring installation and commonly used in extension cord assembly. It comes in a roll of 150 meters and with sizes of gauge # 18 and gauge #16 awg (American wire gauge).

Stranded Wire

made of multiple strands joined together to make a single wire.

Solid Wire

made of a single strand of copper or aluminum wire. These are used in wiring installation inside and outside the buildings.

Conduits/Pipes

electrical materials used as the passage of wires for protection and insulation. These could be rigid metallic, flexible metallic conduit (FMC), rigid nonmetallic (PVC), and flexible non-metallic or corrugated plastic conduit (CPC)

Clamps

electrical materials used to hold and anchor electrical conduits in its proper position.

Connectors

used to attach metallic or non-metallic conduit to the junction or utility boxes.
