Question

Find the equivalent star connection from three 5Ω resistor connected in Delta. ​

Answer 1

Answer:

Let's consider the resistance be R ohms

Since two resistors are in series, the equivalent of this is 2R.

This 2R. Is in parallel with one R resistors

So total resistance is 2R // R

Ie, =(2R*R)/R+2R

=2R^2/3R

=2/3 *R
