Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle electricity as physics and as a supplied utility, with quantities, safety and supply, giving safety guidance first.

The set of physical phenomena associated with electric charge and its motion, including electric current, fields and potential; also electrical energy supplied for use.

What it is for: Powering devices, lighting, heating, industry and communication.

It can be measure voltage, current and power; supply and meter it; use it safely; generate it from various sources.

Distinguishing features

Charge and its motion

Current, voltage, resistance and power

Supplied through grids

Dangerous at mains voltage

What it looks like

Invisible; seen as sparks, lightning and working devices.

Physical character

mains voltage: 100-240 V - varies by country

mains frequency: 50 or 60 Hz - by region

How it is recognised

Voltage and current ratings

Plugs, sockets and meters

Fault terms such as line-to-ground fault

What the second pass must settle

  • Should the physics and utility senses be separate entries?
  • How should electrical quantities be linked?
  • How should safety guidance be localised?
