If the secondary coil of a transformer has fewer coil turns, what effect does it have on the voltage level?

When the secondary coil of a transformer has fewer turns of wire compared to the primary coil, it leads to a decrease in voltage level. This is rooted in the principles of electromagnetic induction and the relationship between the number of turns in the coils and the induced voltage.

In transformers, the voltage ratio between the primary and secondary coils is directly proportional to the ratio of the number of turns in each coil. If the secondary coil has fewer turns, it will exhibit a lower voltage than the primary coil. This lowering effect is a principle known as stepping down the voltage.

Voltage transformation can be summarized with the formula:

[

\frac{V_p}{V_s} = \frac{N_p}{N_s}

]

Where ( V_p ) and ( V_s ) represent the primary and secondary voltages, respectively, and ( N_p ) and ( N_s ) represent the number of turns in the primary and secondary coils. If ( N_s ) (the number of turns in the secondary) is smaller than ( N_p ) (the number of turns in the primary), the voltage ( V_s ) (secondary voltage) will be less than ( V_p ) (primary voltage), thus stepping down the
