A transformer without power loss carries 4000 turns in the primary and 2000 turns in the secondary. If the primary voltage is 120 V and the current is 0.2 A.a. What is the output voltage of transformer?b. What is the current in the secondary?c. What is the maximum output power?d. Where are the thick wires to be used in this transformer in the primary or secondary? Why? |

Answer» a. 60 V, \(\cfrac{Vs}{Vp}\) = \(\cfrac{Ns}{Np}\) Vs = \(\cfrac{Ns}{Np}\)\(\times\)Vp = \(\cfrac{2000}{4000}\) \(\times\)120 = 60 V b. 120 V \(\times\) 0.2 A = 60 V \(\times\) Is Is = 0.4 A c. P = VI = 60 \(\times\) 0.4 = 24 W d. In the secondary. Since P = V1 current is more in the secondary. |
