Hello.
So before we jump in to commercial and start making the circuit, let me explain you how council works
in dealing with the circuit.
So we already discussed the basic theory of the circuit.
So let me just redraw the circuit.
Uh, OK, so here we have the circuit and we generally need to add a ground in the circuit.
So let me add, uh, resistance and then let me ground the circuit, OK?
Now, the first thing comes in will find the nodes.
So for each component, you need to have nodes where it is being connected.
So let me just name denotes that this is one node.
This is another node.
Uh, the circuit, you know, the switch doesn't matter here.
So this will be another node and these two nodes are connected.
So basically, uh, these two nodes are same.
Right.
So here we have node and here we have the ground node.
OK, and here for the ground, we might consider the node for the ground.
So if we simplify this model, how does this look?
So we have a water source, we have our resistance and then we have a capacitor.
The capacitor is basically connected here.
We have a register and then we have, uh, ground.
So this is one.
This is two.
This is three.
This point is four.
And let's say at the end of the ground is five.
So we have five nodes.
So one and two, we have the voltage between one and two.
Between two and three.
We have the Reston's between three and one.
We have the capacitor because, you know, this is the same wire.
So we can write that.
The one is basically this.
So let me just erase this.
OK, so between four and five, I use the ground and between one and four we have the R two.
OK, so just remember the circuit and let's jump back to council and we'll try to make this circuit,
OK?
So now we are in the world of Khamsin and we have already added the physics for the electrical circuit
and by default, always a ground naughties added.
Right.
So let's start we'll start by adding a voltage source.
OK, because, uh, we had a folded source and we will name the node as one and two.
OK, it is already named as one and two.
And let's say the voltage is one four.
OK, this is totally fine.
And then we will.
Right.
Click on the circuit again and we will add the second component that is the disaster, and we will connect
the resistor from two to three.
So one side is two and the other side is three.
OK, uh, now, while you solve a very complicated circuit, try to take a smaller loops and move from
clockwise to anticlockwise or from anticlockwise to clockwise, just try to follow a pattern.
Otherwise you might get confused and the default resistance is one.
So this is fine.
We are just, you know, learning this.
We can change it anytime if we need to.
So let me add a capacitor so either you can.
Right click and add a capacitor or you can click on the electrical circuit at the top and then you have
all the components you can select capacitor and the capacitor will be added in the physics.
Similarly for the capacitor.
We have three and it is connected to one.
OK.
And then we have another instr, so I click on Easter and Easter two is added, the second Easter is
connected from one, the other end is connected to four.
Right, and let it be one day or I'll just make it 10k fight and the ground, the ground is connected
to four.
OK, this is the single node which is the ground.
So the ground is for we don't need five five.
So now we need to study the circuit to study the circuit.
Uh, we have to first look at the circuit and see if it is time dependent, if it is frequency dependent,
what are the computers involved in it?
Where do the residents curve occur?
If there is any resonance?
And if we want to study the charging upper capacitor, we have to see at what time range should we run
the simulation so that we can clearly see the charging of the circuit and so on.
So in my next lecture, we will add the study, which is very important.
The settings in this study is very important because it actually depends on the circuit, which we are
adding.
So, for example, when you're working with thermal modules in so it is more or less time dependent.
Right.
But in electrical circuit, it could be dependent on multiple factors, depending on the components
you are using.
So, OK, uh.
So we'll be back in our next lecture and in our next lecture, we'll learn how to study and then we
will run our simulation.
