A wire of resistance $18$ $Ω$ is divided into three equal parts. These parts are connected as sides of a triangle, the equivalent resistance of any two corners of the triangle will be

Options:

Answer:

Solution:

To find equivalent resistance across

BC, AB and AC is in series

$R^{'} = 6 + 6 = 12 Ω$

$12 Ω a n d 6 Ω$ is in parallel

Total resistance,

$R = \frac{12 \times 6}{12 + 6}$

$R = \frac{72}{18} = 4 Ω$
