Hello I will be taking Circuits next semester. I am trying to work around a circuits book by myself. Now I hope this is the right section to post it (its not homework, just a concept I have problem understanding). I know that to check resistance in series I need to add the resistor value. and in parallel the total resistance will be the reciprocal of each resistor. Is it possible to measure a circuit without any given resistor values. If I am measuring the resistance of two or more resistors in series (or in parallel) what will be the best method to get approximation or exact values for whole of the resistors? Thank you for your help.
