TLE; Chapter 4 (Electrical Signs and Symbols) Flashcards
It is a picture or symbol intended to warn or alert people of a potentially hazardous condition and help an individual operate a tool/s better and safer
Electrical sign
It is for the safety of an individual
Electrical sign
It is crucial for anyone who interacts with electricity
Electrical sign
These are the types of electrical signs
Caution, Safety Alert, Prohibition, Danger, High Voltage, Electrical Hazards
Indicates some precautionary measures against potential hazardous situation which, if not avoided, may result to a minor or moderate injury
Caution
Indicates that a person should observe extra awareness
Safety Alert
It means that any activity is not allowed as stated by the symbol
Prohibition
Specifies hazardous situation which, if not avoided will result to a serious injury or even death
Danger
Warns of dangerously high voltage that can cause serious injury
High Voltage
To prevent accidental contact or misuse of electrical equipment
High Voltage
Informs workers and visitors of electrical hazard in the facility
Electrical Hazards
Examples of these are Electrical Shock, Overloaded Circuits, Faulty Equipment
Electrical Hazards
These are small drawings or pictograms used to represent various electrical devices in a diagram or plan of an electrical circuit
Electrical Symbols
Used in planning buildings
Electrical Symbols
The main purpose of this symbol is to make the circuit to the “open” condition or to the “close” condition
Switch
This is the source that mainly develops the charge for the circuit
Cell
It is a single electro chemical unit that converts chemical energy to electricity
Cell
It is a multiple connection of cells
Battery
It is a connection between a few cells
Battery
It is more energized than a single cell
Battery
The ____ will light up when the electrical charge is flowing through this
Lamp
It is a safety component
Fuse
It has a lower melting-point wire in it
Fuse
It is an instrument that measures voltages of either direct of alternating electric current
Voltmeter
A device used for measuring electric current in amperes, either direct (DC) or alternating (AC)
Ammeter
Only one direction of current
Direct Current
Periodically changes directions
Alternating Current
An electrical component that is passive and adds resistance to the flow of a current
Resistor
