Question

Write a MATLAB script that can determine R in the resistance between terminals a and b in figure p18.13 is 75 ohms.

Answer 1

w 1200 402 Rab= 752 Randbon resistance are in Series - Spree 12052, 4on and Combination of Rand 5 are in parallal Then equivalent resistance of 120.00, you and (R+52 is given by 1 - 1 1 0 1 1 1 0 + R15 2+5 30. (R+5) 30+ R15 = 30R+ 150 R+ 35 R1 -- Now herce Rand R are in series Equivalent Resistame aand is given by Rab 75 = R+R - R+ 3OR1150 J R+ 35 75 (R+35) - RR+35)+30 R+ 150 75R+ 2625 = R² + 35 R +30 R+ 150 R-18 - 24750 т.

R²-558+45R-2475=0 RR-55) +45 (R-55) =0 (R-55 (R+45) = 0 - R = -45,55 since Resistance can not be negative Hence (R = 552 AM
