These are the questions and I don't want someone to just give me the answer. I just genuinely dont understand the questions or where to begin with them. Any help would be greatly appreciated. if someone could explain what RL<<R2 and RL>>R2 means as well that would be nice

I would post my best attempt but I genuinely don't know where to start

Think about it .... How would you represent the equation for R2 and RL in parallel? Substitute that equation for every occurrence of R2 in the equation you provided int post #1

Here is how to begin.

Without using actual numerical values, write out every equation you can think of using algebraic variables, Vs, R1, R2, R3.
Reserve V1 for voltage across R1, V2 for voltage across R2, V3 for voltage across R3.
Use I1 for current flowing in R1, etc.

What happens when you move the slider RL ?
