What it is Filled
In circuit theory, a pair of terminals through which an electrical network or circuit connects to an external circuit, with current entering one terminal equal to current leaving the other and a voltage defined between the terminals.
Why it exists Filled
Let an agent explain circuit ports, their terminal voltages and currents, and their role in describing connections between electrical networks.
Distinguishing features Filled
- Each port consists of a pair of terminals.
- The current entering one terminal equals the current leaving the other.
- Port voltage is defined between the two terminals.
- A network may be represented using one or more ports.
What robots and AI may and may not do Filled
Must not
- Assume that any two terminals satisfy the port condition.
- Confuse circuit-theory ports with network service numbers or software interfaces.
- Treat an abstract port model as proof that a physical connection is safe.
- Authorize physical circuit changes beyond its assigned authority.
Only with a human decision
- Safety-critical decisions about physical circuit connections require a qualified human.
May
- Explain circuit ports and the equal-current condition.
- Interpret port voltage and current conventions in circuit models.
- Describe one-port and multiport network representations.
Moral aspects Filled
- Incorrect circuit models can endanger people and damage equipment.
- Model assumptions and reference conventions should be explicit.
Who is affected
- People working with the circuit are affected.
- Equipment owners are affected.
- Users of connected equipment are affected.
Owners Filled
Steward
The responsible circuit designer or equipment owner oversees the applicable circuit model and physical implementation.

Plane XCT: no invented physical properties.
Recognition optional Filled
- A circuit diagram may show a port as a pair of terminals at a network boundary.
- Voltage polarity marks and current arrows may identify the port's reference conventions.
- A physical socket or numbered network service does not by itself identify a circuit-theory port.
- Sockets on devices; numbers in network configuration.
Capabilities and actions required Filled
- explain hardware, network and software ports
- describe standards
- support troubleshooting generally
- separate other senses
Hazards and failure modes required Filled
- Treating arbitrary terminals as a port without the equal-current condition can invalidate a model.
- Inconsistent voltage polarities and current directions can produce incorrect results.
- Confusing circuit ports with computing interfaces can lead to inappropriate assumptions.
- Physical circuit connections can expose people and equipment to electrical hazards.
Standards and interfaces required Filled
- Hardware interface standards
- Registered port number assignments
- Security guidance on open ports
Context of use required Filled
- Connection points for devices and programs.
- physical hardware ports
- network ports and port numbers
- software and application ports
- serial and legacy ports
- virtual and console ports
