An ac voltage of 24 V is required for a device whose impedance is 12 . (a)

Question:

An ac voltage of 24 V is required for a device whose impedance is 12 Ω.

(a) What should the turn ratio of a transformer be so the device can be operated from a 120-V line?

(b) Suppose the transformer is accidentally connected reversed, i.e., with the secondary winding across the 120-V line and the 12-Ω load across the primary. How much current will then flow in the primary winding?
