An ideal transformer has 600 turns in the primary winding and 40 turns in the secondary winding. If the current in the primary winding is 5\text{ A}, and the primary voltage is 120\text{ V}, what is the current and voltage in the secondary winding?

1. (A)Current in Secondary(A): 1, Voltage in Secondary(V): 15
2. (B)Current in Secondary(A): 8, Voltage in Secondary(V): 75
3. (C)Current in Secondary(A): 60, Voltage in Secondary(V): 8
4. (D)Current in Secondary(A): 75, Voltage in Secondary(V): 8
