Document Summary

To prove maximum power transfer theorem using pspice software with dc parametric sweep analysis. Analysis type: dc sweep / primary sweep/ global parameters/ linear. Vth : _30__ volts; rth : ___10___ . Value of resistance at pmax : __10__ ohms. The power transferred from a supply source to a load is at its maximum when the resistance of the load is equal to the internal resistance of the source. On the other words" a resistive load will be consumptive maximum power from the supply when the load resister is equal to the equivalent (thevenin) network resistor" Procedure: create the given circuit diagram in new project file using the general procedure, replace the default component and source values as per given circuit diagram. Introduce any variable name in load resistance value with in curly braces {}. Select and right click for properties, new column / new row, type the name rl and the value.
