(B)-Indicate whether the following statements are true or false and correct the false statements 1- Two transformer are operating in parallel , their load sharing will depend upon per unit impedance 2- E.M.F per turn (E/N) in H.V. winding is more than the E.M.F per turn in L.V. winding 3- open circuit test in transformer is performed with rated transformer current 4- Transformers are rated in KVA instead of KW because KVA is fixed whereas KW depends on load power factor S- The core losses in a transformer are independent of power factor
