Resistor

Single-phase ideal resistor. Implements Ohm's law v = R i. The most common passive element — use for damping, sensing, and load modelling.

Parameters

Config

Name	Label	Type	Default	Units	Description
`resistance`	R	`double`	`1`	`Ohms` (`Ω`, `kΩ`, `pu`, `S`)	Resistance value. Pick a unit from the dropdown; pu / Siemens conversions read the bases from the Units tab.
`measure_current`	Measure current	enum (`Off` / `On`)	`0`	—	Emit branch current as a simulator observable.

Current Monitoring

Name	Label	Type	Default	Units	Description
`current_name`	Current name	`string`	`I`	—	Signal name for the measured branch current. Change the default `I` when you have multiple measured components — duplicate ids collide.

Units

Name	Label	Type	Default	Units	Description
`S_base`	S_base (MVA)	`double`	`100`	—	System base apparent power in MVA. Used by `pu` impedance / admittance conversions in this component's `computations` block.
`V_base`	V_base (kV)	`double`	`230`	—	Base RMS line-to-line voltage in kV. Used by `pu` impedance / admittance conversions in this component's `computations` block.

Observables

Signal	Type	Default name	Enable	Description
`branchCurrent`	`signal`	from `current_name`	`measure_current`	Branch current through the resistor (A).
