Question

write the formula for a)star to delta transformation b)delta to star transformation​

Answer 1

Answer:

$2 {( \times \times \frac{?}{?} }^{?} 2 \sqrt{5 { - { \sqrt[3 \frac{2 {?}^{?} }{?} ]{?} }^{?} }^{?} }$

Answer 2

Answer:

The relation of delta – star transformation can be expressed as follows. The equivalent star resistance connected to a given terminal, is equal to the product of the two delta resistances connected to the same terminal divided by the sum of the delta connected resistances.
