Answer:
The number of turns in the secondary coil is 48.
(B) is correct option.
Explanation:
Given that,
Number of turns on primary coil= 1000
Primary voltage = 2500 V
Secondary voltage = 120 v
We need to calculate the turns in the secondary coil
Using relation between voltage and number of turns in primary and secondary coil
[tex]\dfrac{V_{s}}{V_{p}}=\dfrac{N_{s}}{N_{p}}[/tex]
Put the value into the formula
[tex]\dfrac{120}{2500}=\dfrac{N_{s}}{1000}[/tex]
[tex]N_{s}=\dfrac{120}{2500}\times1000[/tex]
[tex]N_{s}=48\ turns[/tex]
Hence, The number of turns in the secondary coil is 48.
