Thank you so much! It really helps! Cheer

Why R1 and R2? Why can't you use just a voltage supply?

[HPaisana]

Why is Vo/Vt= -R4/Rt?

[benjwgarner]

At 1:20, why are R1 and R2 considered in parallel? Are you counting the connection through Vs, and can you do that?

[bcrepeau1]

@benjwgarner Yes, he is counting the connection through Vs as a short circuit. When calculating the Thevenin Equivalent you can think of Voltage Sources as shorts and Current Sources as opens.

See the Wikipedia page for Thevenin's Theorem for more info.

@benjwgarner you do that in Thevenin, you go round pass the power supply when finding Rt, and now R1 and R2 are parallel.
