Question

Hey Riuu.... Need some help, please solve this for equivalent resistance

Answer 1

16.

AB is a series combination.

as firstly,

two parallels are here .

first parallel

$\frac{1}{20} + \frac{1}{10} = > \frac{3}{20} . = > \frac{20}{3} ohm.$

second parallel

$\frac{1}{20} + \frac{1}{40} . = > \frac{3}{40} . = > \frac{40}{3} ohm.$

so, in the series A B is

$\frac{20}{3} + \frac{40}{3} = > \frac{60}{3} . = > 20ohm \:$

so the total equilent resistance is 20 ohm .
