Question

Need help in multisim 11?
I want to get the transient response of RL circuit....i can get the increasing exponential graph in multisim 7 during simulation.....but i am getting a decreasing exponential curve(i.e,decay response) in multisim 11 when i do the same procedure as i did in multisim 7.....how can i get the initial or growth transient response for RL circuit in multisim 11 so that i can get increasing exponential curve....which satisfies time constant = L/R

Hello,
The process is the same for any circuit (in this case it is an RC circuit which you sent me). You can find the response on the voltage (which I think it's what you're looking for) at any point of the circuit, as well as any parameter really (R,V,I,L..etc).
Please refer to the image attached (an analysis on the voltage at an inductor and the wires connected to it).
The way to set it up (once you're in the transient analysis set up) is, select the Output tab, under Variables in circuit, you can select which parameters to take. V(1) and V(2) refer to the voltage in the circuit at Net 1/2 (or wire 1/2).
This differs from the voltage change within the capacitor/inductor/resistor. If you would like to see the voltage change of an inductor/capacitor/resistor/etc, you can select under the More options box, the button Add device/model parameter, which will take you to a window to select the device type, its name (in the circuit) and the parameter which you wish to analyse. Once you click on Simulate, you can select Cursor >> Show Cursors, to view information for y and x axis (like rise time, decay time, voltage difference...etc)
Hope this helps,
