Refer to Figure P10.4 on page 562. The Thevenin equivalent circuit for the potentiometer is VT = Voc = xV Req = xRp | (1-x)Rp =
x(1-x) Rp2 / [xRp + (1-x) Rp] = x(1-x)Rp
A load RL will reduce

Comment for P 1.20 (c) -> The current and voltage references for the 4-volt battery are a "load set", so the power output of the battery is p=-iv. The numerical result of the power output is negativ

First we see, from v() = 10R/(100+R) that for R = 8.1 v() = 0.75, so the transient will never reach that value in finite time; therefore R > 8.1. The inequality is too complex for an al
