PLUG AND CHUG (FORMULA FAMILIARIZATION)

$\text{Transformer}\text{relationships:}\frac{\text{Primary}\text{voltage}}{\text{Number}\text{of}\text{Primary}\text{turns}}\text{=}\frac{\text{secondary}\text{voltage}}{\text{number}\text{of}\text{secondary}\text{turns}}$

36. The primary of a transformer connected to 120 V has 100 turns. The secondary has 10 turns. Show that the output voltage is 12 V. This is a step-down transformer.
