In an attempt to boost DC voltage, two students thought of using a transformer to accomplish such feat. The transformer has primary to secondary winding ratio of 1:5. In order to verify the output voltage, the secondary side of the transformer was connected to a resistive load, which potential drop would be measured across an oscilloscope. For the primary side, it was connected to a 9V battery and a switch, as shown in the figure below (Figure 1). switch 9V Battery Resistive Load transformer Figure 1: Circuit connection attempted to boost voltage. Upon flipping the switch, the voltage at the secondary side showcase a sudden surge, subsequently decreases to zero. The students were baffled and checked the entire setup, but found nothing wrong with the connection. Upon flipping the switch again, they noticed another voltage surge, but this time the polarity was opposite to that in the beginning. They report this matter to their supervisor, and the latter told them they were wrong from the beginning. (a). Give reasons on why such setup would not work. (b). Explain the observed voltage surge. (c). Relate the observation in Q4(b) to the suitable laws of Physics.
