Electrical Hazards and Safety Practices

This set of vocabulary flashcards covers essential electrical concepts, circuit components, common hazards, and safety protocols based on the lecture notes.

Electricity

A form of energy produced by moving electrons.

Electric Circuit

A complete path where electricity flows.

Source

The component of a circuit that provides electrical energy, such as a Battery.

Wire

The component that carries electricity through the circuit.

Load

A device within a circuit that uses electricity.

Switch

A device used to open or close a circuit.

Closed Circuit

A complete path where electricity flows.

Open Circuit

A broken path where electricity cannot flow.

Electric Current

The flow of electric charges in a circuit, measured in Ampere ($A$).

Voltage

The push that moves electric charges, measured in Volt ($V$).

Resistance

The opposition to the flow of current, measured in Ohm ($\Omega$).

Conductor

A material that allows electricity to pass easily.

Insulator

A material that resists or blocks the flow of electricity.

Electrical Power

The rate at which electrical energy is used, measured in Watt ($W$).

Electrical Hazard

A condition or situation that exposes a person to the risk of electric shock, burns, fire, or serious injury caused by contact with electrical energy.

Overloaded Outlets

A hazard occurring when too many plugs in one outlet cause overheating and fire risk.

Damaged Insulation

Worn or cracked wire coating that allows dangerous current leakage.

Exposed Wires

Bare conductors that can cause electric shock or short circuits.

Wet Conditions

A hazard where water near outlets or appliances greatly increases shock hazard.

Non-conductive object

Materials such as wood or rubber used to safely move a victim of electrocution if needed.
