MultiSensor ​

Provides combined voltage and current measurements from an electrical circuit.

This component extends a PowerSensor to offer voltage, current and power readings as real-valued outputs. The output v represents the measured voltage, the output i represents the measured current and the output power represents power. v and i outputs are directly sourced from internal voltage_sensor and current_sensor subcomponents, which are part of the inherited PowerSensor. The defining equations from the relations block are:

v = \text{voltage_sensor.v} i = \text{current_sensor.i} power = \text{voltage_sensor.v*current_sensor.i} This component extends from [`PowerSensor`](#) ## Usage `MultiSensor()` ## Connectors * `pc` - ([`Pin`](@ref)) * `nc` - ([`Pin`](@ref)) * `pv` - ([`Pin`](@ref)) * `nv` - ([`Pin`](@ref)) * `power` - This connector represents a real signal as an output from a component ([`RealOutput`](@ref)) * `i` - This connector represents a real signal as an output from a component ([`RealOutput`](@ref)) * `v` - This connector represents a real signal as an output from a component ([`RealOutput`](@ref)) ## Behavior
