Показать описание
Zach with UConn HKN presents an example problem solving for the thevenin equivalent. This is a very important concept so we are making another example problem but this time using dependent sources in the circuit example.

Very helpful and straightforward, explained much better than my prof, thanks

Why isn't the equation 5- 10(i1-20i2)?

Very clear example and explanation thank you. Could you short the independent vintage source and place an independent current source into the A, B terminal? From there do a nodal analysis and use the new V/I relationship to determine thev?

When you put a short in between point A and B at 9:30, will there still be a voltage in between those two points? Can you then solve the circuit by using the Node Voltage method?

I was sooo stuck on my homework and it's not the same question as this but as soon as you pointed out that shorting the resistor means you don't count it I realized that's exactly what I missed. Something so simple but changes the entire problem. Thank you!!

When do the KCL at beginning, why you put 0.5Vb? It should be current in the KCL equation right?

when you get your Vth . y didnt you cut the 20 ohm resistor. ? should be vth =(5- 10(.5Vb)) right?? while Vb is equal to 0.588)

Why don't you calculate R by replacing Vol source with wire (short circuit) and Current source with Open circuit? Does it not work in case dependent source?

5:35, Why I(10 Ohm) + I (20 Ohm) = I (20 Ohm) + I(40 Ohm), why can you ignore the current through 5V source?

how can i3=0.5*Vo, a current cannot be equal to a voltage

at 14:25 cant you solve for i2 with that one equation?

What happens when a dependent voltage source is parallel with a short circuit? Will it still have current?

4:30, i don't know why 13Vb =3Va +10 :((, help me please

I just got here, I didn't watch the video yet, but... how do you do that with the "hologram"???

seriously, please decrease that volume in he beginning. Very annoying and unnecessary
