PotentialSensor

Measures the electrical potential at a connection point.

This component represents an ideal sensor that measures the electrical potential (voltage) at a single electrical pin p. It is characterized by an infinite input impedance, meaning it draws no current (p.i = 0) from the circuit it is connected to. The measured potential at pin p (p.v) is then made available as an output signal phi. This ensures that the sensor does not affect the circuit's behavior while providing an accurate potential reading. The defining equations are

$$\begin{gathered} p.i=0 \\ \varphi =p.v \end{gathered}$$

Usage

PotentialSensor()

Connectors

• p - (Pin)

• phi - This connector represents a real signal as an output from a component (RealOutput)

Behavior

$$\begin{array}{rl}\mathtt{p}\mathtt{.}\mathtt{i}\left(t\right)& =0\\ \mathtt{phi}\left(t\right)& =\mathtt{p}\mathtt{.}\mathtt{v}\left(t\right)\end{array}$$
