A step–down transformer transforms a supply line voltage of 2200 volt into 220 volt. The primary coil has 5000 turns. The efficiency and power transmitted by the transformer are 90% and 8 kilowatts respectively. How many turns are there in the secondary one?

In the transformer shown in the figure, the ratio of the number of turns of the primary to the secondary is N₁/N₂=1/50. If a voltage source of 10 V is connected across the primary, then the induced current through the load of 10 kΩ in the secondary is:
        

1. \(\frac{1}{20}~A\)

2. zero

3. \(\frac{1}{10}~A\)

4. \(\frac{1}{5}~A\)
