The potentiometer Rx (adjustable resistor) in the given figure is to be designed to adjust current ix from 10 mA to 1 A. Calculate the values of R and Rx by setting the potentiometer to its minimum and maximum values. Assume V = 160 V. (NOTE: Choose a combination, which makes the potentiometer most sensitive.) V R ww Rx ww The value of R and Rx are Ω and kQ, respectively.
