HANDTOOLS
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
EXTENSIONCORD
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 handtool
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
PHILIPSheadSCREWDRIVER
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
STUBBYSCREWDRIVER
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
LONGNOSEPLIERS
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

An instrument specially designed for measuring resistance
The needleshape 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 10millimeters (mm) in 1 centimeter (cm)
OHMS
The unit of measurement used to measure electrical resistance
If 1 yard is equivalent to 36inches, there are 108inches 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
PICTORIALDIAGRAM
