R1=10+10+10=30Ω R3=20+20=40Ω (1/Req)=(1/30)+(1/20)+(1/40)=(4+6+3/120)=(13/120) Req=(120/13)=9.23Ω

Q. The total electrical resistance between the points A and B of the circuit shown is

$\frac{L}{4}$

$\propto x$

$\propto x^{2}$

$\propto x^{1/2}$

$R_{1} = 10 + 10 + 10 = 30Ω$ $R_{3} = 20 + 20 = 40Ω$ $\frac{1}{R _{e q}} = \frac{1}{30} + \frac{1}{20} + \frac{1}{40} = \frac{4 + 6 + 3}{120} = \frac{13}{120}$ $R_{e q} = \frac{120}{13} = 9.23Ω$
