In this lesson, we're going to do a transient analysis in the same Secrets of the DC operating point lesson. So we have here the secrets. And we're going to change the operating point Corporation into a transient analysis. So, in order to do this, we're going to simulate a did simulation command. And instead of using here, we click transient. And we choose a stop time.
How does it works? It's perfect performs a nonlinear time domain simulation. What it means it means that we're going to see the voltages and currents vary over time we're going to see lots of these values. So we choose the time of the simulation for how much Time the simulation is going to be run. Let's choose 20 Mili. And we can also choose another parameters like time to start saving data.
Maximum time step but before you we don't choose the program will find the full value in our case, which is a initial simulation where you just click OK. Click here, when we put another simulation here, the program just put a comment, which is the same it means that the operating point simulation is no longer active. So when you perform, click here the running man want to happen he that is that Going to appear this large banner. So, wherever elements of series I select, I can I can plot the voltages and currents of any of them. So, for instance v1 is 12 volts. That's make sense, it is a DC circuit, the voltages and currents must not vary over time where you can lots in the same graph, these voltage V free because of these all both of these voltages are in the same blood. It's very difficult to see the free it's very near mean as one vote, minus one vote.
But we can do another stream Rich's right click and add, add block pain. So click here left click and click v2, v2. We can delete that V free delete is trace. And we can add thoughts pain and they can hear at refresh. So we have here all the voltages in the transients analysis. We can also see the currents.
So the bottom one, let's delete view one. And that's but current for the refree like this, we see that it's constant as it should be because it is a DC circuit in free.com Want milliamps. So, where else we can where else you can see here we can see all the currents as well like the same, the same blood like this. And we can also see another complex expressions plotted here, we can right click the green and instead of I are free we can, but I are free minus I are one. Just see the difference between currents of air free and I run. So, this was the first lesson of transient analysis.
In the next lessons we're going to see voltages and currents weights vary over time in dynamic circuits using capacitors and inductors. And so we're going through the takt. Time, Time variations of voltages and currents.
