- | Remember, we need to step down from the $240 \text{ kV}$ power line to a $120 \text{ V}$ line. This is a factor of 2000. One way to achieve this would be to set $N_P = 10$, and $N_S = 20000$. Due to the huge step down, it may be even easier to design a series of step-down transformers, | + | Remember, we need to step down from the $240 \text{ kV}$ power line to a $120 \text{ V}$ line.
