Astudent decides they would like to have hands - on experience when it comes to transformers .the student takes an iron core (square shaped )and wraps a wire around one side 10 times and call this side the primary side (so np=10). the student takes another wire and wraps it around the opposite side of the iron core 20 times and calls this the secondary side ( so ns=20) the student then hooks the primary side to a 1.50-v lab battery.
a) if the student then used a voltmeter to measure the voltage on the secondary side what voltage should the student measure .
b) if the student uses an amp-meter to measure 200-ma on the secondary side how much current was entering the primary coil ?
