A transformer has 200 windings in the primary and 400 windings in the secondary. The primary is connected to an AC supply of 110 V and a current of 10 A flows in it. The voltage across the secondary and the current in it, respectively, are

Options:

Answer:

Solution:

Voltage across secondary coil is $E_{s} = E_{ρ} \times \frac{N _{s}}{N _{p}} = \frac{110 \times 400}{200} = 220 V$ Current in secondary coil is $I_{s} = I_{p} \times \frac{E _{p}}{E _{s}} = \frac{10 \times 110}{220} = 5 A$
