In a transformer, the voltage across the primary coil is 120 V rms, and the voltage across the secondary coil is 10 kV rms (i.e. 10 000V). The impedance Z of the primary coil is 50 O, and the transformer is ideal (100% power transmission).
(a) What is the number of turn ratio N1/N2?
(b) What is the impedance of the secondary coil?
