Z Load Multisim Verified

Observe the effect of load impedance on voltage drop and phase shift.

The NI Multisim Component Reference and database include several variations of Z loads to accommodate different circuit configurations:

| Load Type | Load Voltage (Vrms) | Current (Arms) | Phase Shift (Current lagging voltage) | | :--- | :--- | :--- | :--- | | Resistive (10 Ω) | 109.1 V | 10.91 A | 0° | | Inductive (10 + j15 Ω) | 96.2 V | 6.66 A | 56.3° | z load multisim

Place a Tektronix oscilloscope. Connect Channel A to the source voltage and Channel B to the voltage across the Z load (the node between the source and load). Run the simulation. You will visually see the current lagging (inductive load) or leading (capacitive load) the voltage.

Multisim offers two primary methods to apply an impedance load: Observe the effect of load impedance on voltage

This experiment perfectly demonstrates why the "Z Load" is not just a theoretical checkbox—it is the cornerstone of modern AC systems.

To get the most out of Z-Load in Multisim, follow these best practices: Run the simulation

A key advantage of the Z Load component is compatibility with Multisim’s analysis. An engineer can sweep the reactance ($X$) from -20 Ω (capacitive) to +20 Ω (inductive) while measuring the load voltage. The resulting plot reveals the resonance point where $X=0$, producing maximum voltage transfer. This feature is invaluable for filter design and impedance matching.
