Question: A step - up transformer is designed so that the output of it's secondary winding is 3 , 0 0 0 Vrms when the primary

A step-up transformer is designed so that the output of it's secondary winding is3,000Vrms when the primary winding is connected to 110 V line voltage.
a) If there are140 turns in the primary winding, how many turns are there in the secondary winding?
NS = Correct turns
b) If a resistor connected across the secondary winding draws an rms current of0.70 A, what is the rms current in the primary coil?
