Basic Electricity, Tools, and Safety

Vocabulary terms covering fundamentals of electrical quantities, common hand tools, splicing techniques, and safety protocols.

Electricity

A form of energy produced by the movement of tiny particles called electrons.

Voltage (V)

The force that pushes electric current, measured in volts ($V$) using a Voltmeter or Multimeter.

Current (I)

The flow of electricity through a wire, measured in Amperes ($A$) using an Ammeter or Multimeter.

Resistance (R)

The opposition to the flow of electricity, measured in Ohms ($\Omega$) using a Multimeter.

Direct Current (DC)

A type of electricity that flows in only one direction, found in batteries, power banks, and solar panels.

Alternating Current (AC)

A type of electricity that changes direction repeatedly, found in household electricity and school electrical outlets.

Combination Pliers

A tool used for cutting, holding, and twisting wires.

Long Nose Pliers

A tool used for holding small wires, bending wires, and working in narrow spaces.

Side Cutting Pliers

A hand tool specifically used for cutting electrical wires.

Flat Screwdriver

A tool used for driving or removing flat-head screws.

Phillips Screwdriver

A tool used for driving or removing cross-head screws.

Electrician's Knife

A tool used for removing wire insulation.

Wire Stripper

A tool used for stripping insulation from a conductor without damaging the wire.

Pull-Push Rule (Tape Measure)

A measuring tool used for determining wire lengths and distances.

Multimeter

A tool that measures multiple electrical quantities, including Voltage, Current, and Resistance.

Electrical Splicing

The process of joining two or more conductors together.

Western Union Splice

A splice used for joining two wires end-to-end, commonly used for long wire connections.

Plain Tap Splice

A splice used for connecting a branch wire to a main wire.

Knotted Tap Splice

A splice that prevents branch wires from slipping when under tension.

Fixture Joint

A joint used for connecting wires to lighting fixtures.

PPE (Personal Protective Equipment)

Safety gear including safety gloves, goggles, shoes, face masks, and hard hats used to protect workers.
