To solve the problem of finding the number of turns in the secondary coil of an ideal transformer, we can use the transformer equation that relates the primary and secondary voltages and the number of turns in the coils. ### Step-by-Step Solution: 1. **Identify the given values:** - Input voltage (primary voltage, \( E_p \)) = 220 V - Output voltage (secondary voltage, \( E_s \)) = 66 kV = \( 66 \times 10^3 \) V - Number of turns in the primary coil (\( N_p \)) = 300 turns ...
