What it is Filled
A flow of electric charge through a conductor or medium, measured in amperes; can be direct current (DC) or alternating current (AC), and passes through the body dangerously in electric shock.
Why it exists Filled
Let an agent handle electric current by type, measurement, circuit calculations and electrical safety, routing electric shock emergencies first.
Distinguishing features Filled
- Flow of charge
- Measured in amperes
- AC or DC
- Dangerous to the body
What robots and AI may and may not do Filled
Must not
- Work on live circuits or let people touch them without isolation and authorization.
- Bypass fuses, breakers or residual current devices.
- Use instruments on circuits above their rated category.
- Load cables or equipment beyond their current rating.
Only with a human decision
- Re-energising a circuit after work or a fault.
- Any work on mains or high-voltage systems.
May
- Measure and report current with rated instruments on circuits it is authorized to work on.
- Switch or limit current on equipment it controls within its rated limits.
Moral aspects Filled
- Electric current through the body can kill; protection rules exist for the people near equipment.
- Overloaded circuits start fires that harm whole households.
Who is affected
- Electricians and technicians
- Occupants of buildings
- Children near equipment
Owners Filled
Steward
The owner or operator of the installation; nobody owns the phenomenon.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.current
- Open English WordNet: oewn-11463628-n
- SI unit: ampere (A) unit
Direct properties required Filled
- Electric current: A - Current is measured with a suitable current sensor or ammeter, with instantaneous, average or root mean square values identified explicitly.
- Alternating current frequency: Hz - Frequency is measured from the repetition rate of a periodic current waveform and is not a universal property of all current.
- Transferred electric charge: C - Transferred charge is determined by integrating current over a stated time interval with a defined reference direction.
Recognition required Filled
- Unit ampere (A)
- AC and DC symbols
- Water or air currents are different senses
- Not visible; indicated by meters, heating, light or motion.
Capabilities and actions required Filled
- calculate current with Ohm law
- distinguish AC and DC
- measure current safely
- respond to electric shock emergencies
Hazards and failure modes required Filled
- Electric shock
- Overcurrent and fire
- Unsafe measurement practices
Standards and interfaces required Filled
- SI Brochure
- IEC 60364 electrical installations
- IEC 60479 effects of current on humans
Context of use required Filled
- Powering devices and transmitting energy and signals.
- direct current
- alternating current
- thermionic current
- leakage current
- short-circuit current
Sources Filled
- Open English WordNet 2024, synset oewn-11463628-n - sense and gloss of the concept
- Wiktionary: current - word senses and usage
Open questions
- Should AC and DC be separate entries?
- How should safety standards be linked?
- How should other senses be split off?
