    Missing resistor in a voltage divider network

    Hi Harold, You clearly have a huge amount of experience and knowledge in this area, my apologies for the reply I’d sent, I was being a bit paranoid. Thank you for the reply, it is very interesting to so how much has changed in the electronics world and it’s difficult to comprehend how far it...

    Missing resistor in a voltage divider network

    Thank you for your help, it was much appreciated. I guess it's kind of obvious when you point it out, the old adage of 'read the question' never loses its importance.

    Missing resistor in a voltage divider network

    Thank you, I did look at this but I couldn't document my reasoning for the 1v across the 1Kohm resistor without calculating the initial voltage drop across the initial resistor and for this I needed the value to find the current

    Missing resistor in a voltage divider network

    Thank you, I was going to post the image but I'm conscious of plagiarism and just wanted to see if there was any guidance. I've been told I can work it out using the Op Amp golden rules, Ohms and Kirchhoff's Laws but as you stated without the Voltage input or current I can't see how! Must be...

    Missing resistor in a voltage divider network

    I hope someone can help. If I have a series of 6 resistors in a voltage divider network and I'm given the voltage supply and five of the resistor values, how do I find the first resistor value in the chain without being given the current?
