    Yep.

    Yes, you are right. It is beyond my level. Thank you very much.

    Finding the voltage of the circuit (resistor ladder)

    A little bit for self-study but not familiar because GCE A level seldom use it.

    Finding the voltage of the circuit (resistor ladder)

    Sorry for the poor resolution. it is -2x/(sqrt (4*gamma+1)+1). What is the hint? Sorry for this question but I really have an interest. Would you tell me more and I just have GCE A level physics and I think this question is out of A level.

    Finding the voltage of the circuit (resistor ladder)

    I have only GCE A level physics background. How can I start to think about it? I do not expect to solve this question but at least how can I start to think from A level physics.

    Finding the voltage of the circuit (resistor ladder)

    The answer is B. My question: (a) What is the basic approach to start to think about this problem: Equivalent resistance? ohm's law? (b) What is the purpose of gamma = R2/(R1+R3) because I have no idea how it uses? (c) Why the answer is an exponential drop of voltage?
