Hi, I am having a bit of trouble solving for an unknown current. Can anyone help me out, thanks. The resistor R in Fig18.56 dissipates 11 W of power. Determine 2 possible values of R (V= 76 V). My attempt so far, 1st loop: 35I-35I1=76 2nd loop: I=[(70/30)+(R/30)]I1 I plugged equation (2) into (1): 81.667I1 +1.1667I1R-35I1 =76...(3) Given that: I1R =11W/I1 plug that into (3): 46.667I1 +12.8337/I1 -76=0 I've tried using quadratic equation to solve for I1, then plugging into P=I^2R to solve for R, but I still keep getting the wrong answer. Please help. Thank you.
