Transformer diagram showing primary coil with N_p = 50 turns and input voltage V_p connected through an iron core to secondary coil with N_s = 500 turns and unknown output voltage V_s
1.

A step-up transformer has Np=50N_p = 50 turns in the primary coil and Ns=500N_s = 500 turns in the secondary coil. The primary voltage is Vp=120 VV_p = 120\ \text{V}. Calculate the secondary voltage VsV_s in volts.
