Question

Write the name / use of the Component / Equipment shown in the figure.

Answer 1

• One way switch:

Used to start/stop current flow and to change the direction of current flow.

• Two-way switch:

Having two or more switches in different locations to control one electrical device.

• Three-pin socket:

Electricity can be supplied to electrical appliances safely.

• Ceiling rose:

Ceiling rose used to make junction points for branching out wires at different places in a circuit. They enable live wire to go in continuation as needed for connecting multiple electrical appliances.

• ELCB:

Helps to break the circuit automatically whenever there is a current leak due to insulation failure or any other reason.

• Regulator:

Regulates or controls the speed of the fan motor.

• Indicator:

Indicator lamp is usually used to reflect the working state of the electric circuit.

• RCCB:

Distinguish between the phase current and neutral current and to break the circuit if needed.

• MCB:

Automatically breaks the circuit whenever there is an excess flow of current due to short circuits or overloading.

• Kit Kat Fuse:

Protecting a circuit against excess current.

• Switchboard:

To control the flow of power.

• Meter:

Instrument used to measure the electrical energy consumed by a house.

• Main switch:

The main power supply of the RC models.

• Bulb holder:

Holding a light bulb or lamp.

• Clamp Ammeter:

The vector sum of the currents flowing in all the conductors passing through the probe.

• Multimeter:

Can measure voltage, current, and resistance.

• AC Voltemeter:

To measure the AC voltage across any two points of electric circuit.

• Wire stripper:

Used to strip the electrical insulation from electric wires.

• Screwdriver $$(*)$$:

Tool, usually hand-operated, for turning screws with $$*$$ shaped slotted heads.

• Screwdriver $$(-)$$:

Tool, usually hand-operated, for turning screws with $$-$$ shaped slotted heads.

• Tester:

Touched to the conductor being tested to check if current or voltage is flowing through it.

• Pliers:

For gripping something round like a pipe or rod, some are used for twisting wires.

• Gloves:

Leather protector gloves - Worn over rubber insulating gloves to help provide the mechanical protection needed against cuts, abrasions and punctures.

• Insulation tape:

To insulate electrical wires and other materials that conduct electricity.

• Wire (cable):

To carry electrical currents.

• PVC Pipe fittings:

Used to connect PVC pipes together or provide and junctions for the pipes.

• PVC channel:

Used as the insulation on electric wires. They are mounted on the walls to make a systematic way for wires to be fixed.

• PVC Pipe:

Used as the insulation on electric wires. They are mounted on the walls to make a systematic way for wires to be fixed.
