# three register 4 ohm each are connected in the form of equilateral triangle find the distance between the corners

Dear student,

Suppose we need to find the equivalent resistance between A and C.

Resistance in AB and BC are in series. So, they make net = 4 + 4 = 8 Ω

This 8 Ω and AC are in parallel.

So, the required equivalent resistance is = (8)(4)/(8+4) = 2.67 Ω

Regards
