Electrical Hazards, Energy Loss & Energy Wastage

Vocabulary-style flashcards covering electrical principles, hazards, safety practices, and energy conservation based on the lecture material.

Electricity

The movement of electrons between atoms through a wire or a conductor.

Electrical conductors

Materials, often metal, where electrons are free to move and carry an electrical charge.

Electrical insulators

Materials like rubber and plastic that cannot conduct electricity because their electrons are not free to move.

Electrical Hazard

Any dangerous condition involving electricity that can cause injury, burns, fire, explosions, or even death.

Damaged Insulation

When the protective non-conductive plastic, rubber, or polymer coating surrounding a wire has worn down, cracked, melted, or torn.

Overloading

A hazard that happens when too many appliances are connected to one outlet or extension cord.

Damp Electrical Condition

Risky situations including using appliances with wet hands, keeping equipment near sinks, or exposing devices to rain.

Faulty Wiring

An electrical hazard involving loose connections, damaged conductors, incorrect installation, or deteriorated wiring.

Faulty Wiring Warning Signs

Indications such as sparking, burning smell, buzzing, crackling, hot outlets, or flickering lights.

Institute of Integrated Electrical Engineers of the Philippines

The organization whose guidelines should be consulted instead of attempting DIY repairs on structural wall wiring.

Electric shock

A condition that happens when electrical current passes through the body.

Electrocution

Death resulting from electric shock.

Energy loss

A process where energy is transformed into another form, such as heat, because of resistance or other physical processes.

Energy wastage

When energy is consumed without providing a useful benefit, such as leaving lights on in an empty room.

Electrons

Negatively charged particles found in all materials.

Severe Electric Shock Effects

Critical physical reactions including cardiac arrest, difficulty breathing, and death.

Electrical Safety First Aid (Step 2)

Use a dry wooden stick or plastic object to separate a victim from a live electrical source.

Minimizing energy loss

Improving how efficiently electrical energy is converted and used.

Minimizing energy wastage

Avoiding unnecessary electricity consumption.

General electrical safety tips

Practices such as reading appliance instructions, keeping cords organized, and wearing rubber-soled shoes while working with electricity.
