Electricity and Magnetism Fundamentals

Vocabulary flashcards covering core terms and definitions in electricity, circuits, electromagnetism, and electrical machines.

Conductor

A material that electricity can flow through easily. These materials are made up of atoms whose electrons can move away freely. Some examples of conductors are: Copper and Aluminum.

Magnet

An object that produces a magnetic field, which can attract or repel other magnetic materials.

Solenoid

A coil of wire that generates a magnetic field when electric current passes through it.

Motor

A device that converts electrical energy into mechanical energy (motion) by induction.

Generator

A machine that converts mechanical energy into electrical energy by induction.

Turbine

A machine with rotating blades that captures the energy of moving fluid (like water, steam, or air).

Induction

The process of generating an electric current using a moving electric or magnetic field.

Electron

Negatively charged particle that moves through conductors, creating electric current.

Circuit

A loop through which current can flow.

Voltage

The "push" that drives electric current through a circuit, measured in volts (V).

Current

The "flow" of electric charge, measured in amperes (A).

Resistance

The opposition to the flow of electric current in a material, measured in ohms (n).

Power

The rate at which electrical energy is transferred or used, measured in watts (W).
