Please sir, at 9:10 i don't understand why did we take v2 to be negative? and do we always consider at 8:37 that there will be positive up and negative down?
@SkanCityAcademy_SirJohn
Ай бұрын
At 9:10 Ideally the current is supposed to flow from the positive terminal at V2. But since we take 2v as reference voltage and we take the clockwise direction, V2 will move opposite to 2v hence V2 will be negative. At 8:37 Yes, negative is to ground.

Please sir For the first eg. Can there be a case where the 2A is directed downwards or the 7A is directed upwards. If yes ,how are you gonna solve it
@SkanCityAcademy_SirJohn
Жыл бұрын
Yes, the difference is where you apply kcl and the node. If one quantity is entering the node and was positive, if the direction changes, it will be leaving the node and this time negative

We have to demand corrections on books and ideas. In real world, there is no such thing as current source without voltage source. A circuit showing only a current source is fake idea. Where can you find a current source? This idea is meant to confuse students.

He has a point. I have this in my own notes concerning current sources. I think it would be safe to say that inherent within the symbol of the current source there is a Voltage. Since Voltage is a requirement for all circuits, including current sources, current source is just a specialized application of a Voltage source. 😅, did I confuse you more 😂

When a voltage source is found between two node reference nodes, a supernode is formed. In this case, the element in parallel with the voltage source goes away.

Since there is a voltage source in between the two non-referenced nodes, a supernode is formed, hence a supernode is formed and the element in parallel with the said voltage source goes away.

We assume conventional flow of current which says that current leave the positive terminal of a voltage source, an thats a positive current. Reference source is the 2v. We take the clockwise direction, going round the loop, our reference current opposes that of v2 hence that becomes negative and that of v1 is in line with the direction we took, ie. Clockwise, hence v1 becomes positive.
