2. STAR – DELTA TRANSFORMATION Dr. Vinika PROFESSOR DEPARTMENT OF PHYSICS Sanskriti College , Jaipur Nishant katara Student B.SC. (H) CHEMISTRY

3. STAR – DELTA TRANSFORMATION also known as T- ∏ transformation. they are some complex networks whose equivalent resistance can`t be found by using simple series – parallel technique. to solve such complex networks , star-delta ( T- ∏ ) transformation technique is used.

4. STAR (T) NETWORK

5. DELTA (∏) NETWORK

6. USING T-∏ TRANSFORMATION , T - connection can be converted into ∏ - connection OR ∏ - connection into T – connection

7. DELTA – STAR TRANSFORMATION

8. R 1 = R a R B / R a + R b + R c R 2 = R a R c / R a + R b + R c R 3 = R b R c / R a + R b + R c

9. STAR – DELTA TRANSFORMATION

10. R a = R 1 + R 3 + R 1 R 3 /R 2 R b = R 1 + R 2 + R 1 R 2 / R 3 R c = R 2 + R 3 + R 2 R 3 / R 1
