Answer:
<em>The primary coil has 13,400 turns</em>
Explanation:
<u>Voltage Transformers</u>
A transformer is an electrical apparatus that converts an alternating electrical voltage to another. Step-down transformers lower the voltage from higher levels (kilovolts) to consumer levels (120/240 Volts).
The ratio between both voltages can be computed as
Where V1 is the primary voltage and V2 is the secondary voltage. This ratio depends on the turns ratio of the coils wounded in a common magnetic core.
Being N1 the number of turns of the coils of the primary side and N2 the number of turns in the secondary coil. Both relations give us
Solving for N1
We have:
Calculate N1
