A transformer has a primary coil with 108 turns and a second

A transformer has a primary coil with 108 turns and a secondary coil of 354 turns. The AC voltage across the primary coil has a maximum of 126 V and the AC current through the primary coil has a maximum of 3 A. What are the maximum values of the voltage and current for the secondary coil? voltage V current A

Solution

Number of truns in primary coil N = 108

Number of truns in secondary coil N \' = 354

Voltage across primary coil V = 126 volt

Current through the primary coil i = 3 A

We know V / V \' = N / N \'

From this maximum value of voltage across the secondary V \' = V ( N \' / N )

V \' = 126(354/108)

      = 413 volt

We know i / i \' = N \' / N

maximum value of current through the secondary coil i \' = i ( N/N \')

     i \' = 3 ( 108 / 354)

        = 0.9152 A
