Description

pict

The Ammeter measures the current through the component and provides it as a signal at the output. The direction of a positive current is indicated with a small arrow in the component symbol. The output signal can be made accessible in Simulink with an Output block or by dragging the component into the dialog box of a Probe block.


Note  The Ammeter is ideal, i.e. it has zero internal resistance. Hence, if multiple ammeters are connected in parallel the current through an individual ammeter is undefined. This produces a run-time error.

Likewise, if switches connected in parallel are all in closed position the current through the individual switches is not properly defined. Although this does not produce a run-time error it may lead to unexpected simulation results.
