A step up transformer used in an automobile has a potential difference across the primary of 2200 V and a potential difference across the secondary of 25 V. What is the ratio of the numbers of turns of wire on the primary to the secondary?
2 answers
N1/N2 = V1/V2 = 2200/25 = 88/1.
Based on the information given, this is a step-down transformer.
