2012 Calculate the final equivalent resistance between terminals A and B? Ensure that you draw out each step. You should follow the process: a. Identify the parallel resistors using their labels and the parallel symbol notation (e.g. Rx = R1 || Rs), then work out the equivalent values for the parallel resistance(s), using your designated labels (e.g. Rx = 492). b. Redraw the circuit with the parallel resistors replaced by their equivalent resistance(s). Hint: replacing parallel resistors does not remove...
