A transformer with 600 turns on the primary coil is used to decrease the voltage from 3000 V to 120 V for home use. How many turns should be in the secondary coil?

Question

Quizplus · Accepted Answer

The number of turns in the secondary coil can be found using the transformer equation: $V_p/V_s = N_p/N_s$, where $V_p$ and $V_s$ are the primary and secondary voltages, and $N_p$ and $N_s$ are the primary and secondary turns. Substituting the given values: $3000/120 = 600/N_s$, solving for $N_s$ gives $N_s = 24$ turns.
