Answer to Question #75991 in Quantum Mechanics for RANNN

Question #75991

In an ideal 3:17 step-up transformer, the primary power is 34 kW and the secondary current is 30 A. The primary voltage is:

A. 6.25 V

B. 200 V

C. 1133.3 V

D. 6422.2 V

E. 51 V

Expert's answer

I_pri=30/17 3= 5.294 A
V_pri=34000/5.294= 6422.2 V
