  • PORTABLE ELECTRIC DRILL
    A drilling machine used in making holes on metal sheet
  • HAND TOOLS
    Tools manipulated by our hands without using electrical energy
  • FUSE
    A protective device that automatically blows and cut current when an overload or short circuit happen
  • EXTENSION CORD
    A power cord that uses a span of flexible power cable with a plug on one end and multiple sockets on the other end
  • VACUUM CLEANER is NOT an example of a hand tool
  • SWITCH
    A device that connects and disconnects the flow of electric current in a circuit
  • CONVENIENCE OUTLET
    A device that acts as a convenient source of electrical energy for current consuming appliances
  • ELECTRIC BREAKER
    Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire
  • PHILIPS head SCREWDRIVER
    A cross-tip tool resembling a positive (+) sign, used to drive screw with cross slot
  • ELECTRICIANS KNIFE
    A tool used by a lineman to remove insulation of wires and cables in low and high voltage transmission line
  • STUBBY SCREWDRIVER
    It comes in either Standard or Philips screwdriver with short shank or blade and a shorted handle used to turn screws in tight space where standard screwdriver cannot be used
  • LONG NOSE PLIERS
    Used for cutting and holding fine wires. Can reach tight space or small opening where other pliers cannot reach and used in making terminal loops of copper wires
  • 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
  • UTILITY BOX
    A rectangular shaped metallic or plastic (PVC) material in which flush type convenience outlet and switch are attached
  • HAMMER
    A tool used in driving or pounding and pulling out nails
  • Multi-tester
    A measuring tool used to measure voltage, resistance and current. It is sometimes called VOM
  • OHM-METER
    An instrument specially designed for measuring resistance
  • The needle shape rod that moves over the scale of a meter

    POINTER
  • RULER
    Measurement tool used to measure the length of an object in centimeter and inches
  • AMPERE
    The unit of measurement used to measure electric current
  • If 1 inch is equivalent to 2.54 cm, there will be 30.38 centimeters in 1 foot
  • In a metric unit of measurement, there is 10 millimeters (mm) in 1 centimeter (cm)
  • OHMS
    The unit of measurement used to measure electrical resistance
  • If 1 yard is equivalent to 36 inches, there are 108 inches are there in 3 yards
  • Ampere
    A measuring instrument that measure the amount of electric passing in a certain point at a particular time
  • LAMP-HOLDER

    A device that holds and protect the lamp and are also called as Lamp Sockets/Receptacles
  • PARALLEL CIRCUIT
    A type of circuit in which lamps are connected across the wires
  • SERIES CIRCUIT
    A type of circuit in which lamps are arranged in a chain, so that the current has only one path to take. The current is the same through each load
  • The advantage of using parallel circuit is that even if one of the lamps fails, still the remaining lamps will function
  • PICTORIAL DIAGRAM
    A type of diagram which the sketch of electrical circuit that shows the external appearance of each component
  • Schematic DIAGRAM
    A type of diagram showing the components of the circuit using standard electrical symbols
