In a step up transformer, primary power is 50 W and output voltage is 100 V. If the current in the primary is 1 A.a. What is the primary voltage? b. What will be the current in the second ary?c. \(\cfrac{Secondary\,power}{Primary\,power}\)= ? |

Answer» a. P = Vp × Ip 500 W = Vp × 1A, Vp = 500 V b. Is = \( \left(\cfrac { I_p × V_p }{ V_s }\right)\) = \(\cfrac{1 \times 500}{100}\) = 5A c. Primary and secondary powers are equal \(\cfrac{Secondary\,power}{Primary\,power}\) = 1 |
