In this part of the lab, we will "take measurements" and perform calculations in order to determine the efficiency of a transformer. The efficiency (7) of a transformer is the ratio of power out to power in: Vout X Iout Vin x Iin The efficiency is therefore a ratio between 1 and 0. THE FOLLOWING ESSAY QUESTION IS WORTH 1.5/10 OR 15% OF YOUR OVERALL LAB MARK Essay Question 1: There are many DESIGN factors that affect the efficiency of a transformer. (A design factor is something the maker of the transformer selects, like the thickness of the wire, or the colour of the magnetic core). 7 = Pout Pin Choose a design factor that affects the efficiency of a transformer, and explain why it has an impact. You should explain what choice would make a transformer more efficient, and what choice would make a transformer more inefficient. Your answer should have three components, 1) The design factor you have chosen. 2) An explanation as to why this design factor impacts the efficiency of a transformer. 3) An outline as to what choices will improve the efficiency of the transformer for this design factor.
