Question

A wire has a resistance of 6 ohms. It is bent in the form of an equilateral triangle. The effective resistance between any two corners of tha triangle is

Answer 1

Heya!!

If total resistance of wire = 6 ohm,

Then each side of an equilateral triangle have 6/3 = 2 ohm..

Diagram : attachment 1.

If we choose BC.

Then AB and AC are in series with BC.. Attachment 2..

Hence 1/R = 1/2 + 1/4

=) 1/R = 3/4 ohm

=) R = 4/3 ohms

Hope it helps uh!!
