A transformer has a primary coil with 175 turns of wire and a secondary coil with 1,400 turns. An AC voltage source connected across the primary coil has a voltage given by the function v = (180 V)sin(ωt). What RMS voltage (in volts) is measured across the secondary coil?
a) 14.14 V
b) 16.97 V
c) 24.25 V
d) 28.28 V
