Answer:

Explanation:
<u>Given the following data;</u>
Number of loops in primary coil, Np = 1 loop.
Number of loops in secondary coil, Ns = 8 loops
Voltage in secondary coil, Vs = 120V
To find the voltage in the primary coil, Vp;
Transformer ratio is given by the formula;

Making Vp the subject of formula;

Substituting into the equation, we have;



Therefore, the voltage in the primary coil, Vp is 15 Volts.
