A transformer has a ratio of 4:1. The high voltage side is connected to a 240 Vrms source. The low voltage side (secondary) is connected to an impedance ZL = 20 + j10 Ω. a. (in Vrms) What is the value of the source voltage when referred to the secondary? b. (in A rms) What is the current at the secondary? c. (in V rms) What is the voltage at the secondary?
