What it is Filled
The difference in electric potential between two points, which drives electric current through a circuit, measured in volts (V); examples include battery voltages, mains supply of about 230 V in Europe and 120 V in North America, and high-voltage transmission lines.
Why it exists Filled
Let an agent explain voltage by definition, measurement and everyday values, and route electric shock and electrical hazards to emergency help and qualified electricians.
Distinguishing features Filled
- Potential difference
- Measured in volts
- AC or DC
- Higher voltages are more hazardous
What robots and AI may and may not do Filled
Must not
- Work on or advise untrained people to work on live mains or high-voltage equipment.
- Bypass isolation, earthing or protective devices.
- Connect devices to a supply voltage they are not rated for.
- Approach high-voltage lines or equipment closer than safe distances.
Only with a human decision
- Energising or isolating a circuit that others may be working on.
May
- Measure and report voltage on equipment it is authorized to work with, using rated instruments.
- Explain supply voltages in different countries and when a converter is needed.
Moral aspects Filled
- Electric shock kills; voltage safety rules protect workers and households.
- Unsafe wiring causes fires that harm neighbours too.
Who is affected
- Electricians and maintenance workers
- Households
- Children near electrical equipment
Owners Filled
Steward
Nobody owns the quantity; the network operator answers for the supply and electrical safety regulators set the rules.
