Jargon buster
Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale from 0 to 14 where 7 is neutral, lower is acidic and higher is alkaline. When a probe or sensor quotes a pH range and accuracy, check they cover the readings your project needs.
