A step-up transformer used in a car has a potential difference of 10 V across the primary coil with 12 turns. What is the current in the secondary coil of resistance 2.5 Ω if the number of turns in the secondary coil is 54 turns?

factors of 6: 1, 2, 3, 6 1 x 2 x 3 x 6 = 36

4(10 + 6) 2(20 + 12) basically take a common factor between 40 and 24 and divide
