Electric Tech and Micro:bit Vocabulary

Front

Circuit

Back

A path that allows electricity to flow from a power source through various components and back to the source.

Front

Series Circuit

Back

In a series circuit, the same amount of current flows through each component in the circuit. If one light goes out, they all go out.

Front

Parallel Circuit

Back

The voltage is equal across each parallel component. One lamp can be turned off while others stay on.

Front

Current

Back

The flow of electric charge through a conductor, measured in amperes (A).

Front

Voltage

Back

The force that pushes electric current through a circuit, measured in volts (V).

Front

Resistance

Back

The opposition to the flow of electric current, measured in ohms (Ω).

Front

LED (Light Emitting Diode)

Back

A small electronic light source that lights up when an electric current flows through it. Used in micro:bit to display information.

Front

Micro:bit

Back

A small, programmable computer designed for educational purposes with built-in sensors for creating electronic projects.

Front

Pin

Back

A connection point on the micro:bit used to send or receive electrical signals, connecting to other components.

Front

Sensor

Back

A device that detects changes in the environment and converts them into electrical signals. Micro:bit has built-in sensors.
