## Definition

the system of paths that electricity flows through inside a machine or device. It is like the network of wires and parts that makes your phone or computer work.

For teachers: a system of electric circuits or the arrangement of components within an electronic device. Refers to the physical layout and interconnected paths that facilitate electrical signals.

## Examples

- The water damaged the phone's internal circuitry.
- Engineers are working to shrink the circuitry so the new laptop can be even thinner.
- The failure was traced back to a microscopic flaw in the motherboard's circuitry, which caused an intermittent short circuit during high-voltage operations.
