In this lesson, we're going to do a this year operating point analysis. So first thing we're going to do is click here on your schematic and we're going to draw a simple DCC upwards. Register. And that's some of them. Breast contour, err, cheaper to restore and there are reasons though, breast esky to choose another component and then we click here and we put voltage voltage source here and rotated with contour air supports here. And then we click the pencil to put wires and connect all the components Past key and then you shouldn't forget that grounds which serves as the voltage reference connected ASCII.
And then what are we going to do? We must put the values of the registers and the voltage sources. Right click and then we're going to put let's say two kilo ohms three kilo ohms four kilo ohms Thank you alarms. And now this voltage 12 volts, five volts. Now, in order to do a operating point analysis we must go to simulate Did simulation command and chose the last one this year breaking point. It reads that it's computes that this year breaking points treating capacitances as opensecrets and inductances short circuits.
It means that if we had, we don't have but if we have, if we had capacitors and inductors, they would be treated as opposites and short sequences respectively. Because in this analysis, we're interested in the effect of DC sources on the circuits. And then find, which is the operating point of the circuits, operating voltage and current. So we're going to click OK here and left click anywhere and then click the Run the men just simulate. So we get Is information, the voltages and the currents? That one thing that isn't so clear is with node is this voltage related to we don't know for sure.
So, one thing we could do to ease our understanding is click label nets Japan some names to children nodes. So we put here v one, like this, ask, vid to hear the free ask, just make it clear that when we put the same label net in two different nodes, two separate nodes want to work going to do in practice is that we're connecting these nodes. So, if we had v one here, the effect would be the same of not having the labor here, but having a wire connecting these nodes. But in this example, it isn't the case. So, we take the scissor to cut and we love this wire as key and but again the cheer like this as key, so we can simulate it again. Press the running man.
And we have V or V tree here, minus one dot zero free votes, approximately. voltage of veto Free that 996 voltage v1 here, this one Trove. And then we have all the currents here we can see that the difference between between the voltages of v2 and v3 is exactly five volts as it should be because it's a five volt voltage loss. Another useful feature of the program is that we can place the mouse cursor above the element and we can see here on the left, look at the left, down left, we have the current i air for it's approximately 850 three meter amps. And it's also shows the dissipation and microbots, approximately six dot 45 microbots. And then the simulation, we can change some parameters to see what happens in the variables of the secrets.
For instance, we can change these resistance to eight and then click OK. Now the current is 800 and the free me cramps but let's run again to see if it increases or decreases. Ran. And we have 978 he grabs Oh, so we had an increase on the current at this time Our farm meters can be done in every element you do choose. So in this example, we saw first analysis of this program made here, apply that your ADC secrets, it's very useful for your tour verify for a simulation or for a computer simulation, where all the fury behind electricity or grades like nada analysis, mesh analysis, they kick off current law kick ass Voltage Law and so on. The the values you you get here are the ones you're supposed to get from calculation using their fury. So this was the first lesson using the DC operating point analysis.
