Answer:

A step-down transformer converts 2200v transmission line voltage to 220 volts. The number of turns  in the secondary coil is 500, the number of turns in the primary coil is 5000v

​​Explanation:

  • In a transformer, there is a primary coil with a number of turns N_{1} voltage, and current through it is I_{1}. In the secondary coil, the number of turns is N_{2} voltage is V_{2} and current is I_{2}
  • The relation connecting these parameters is given by the formula

        \frac{N_{1} }{N_{2} } =\frac{V_{1} }{V_{2} }=\frac{I_{2} }{I_{1} }

From the question, we have

the voltage in the primary coil is V_{1} =2200v

the voltage in the secondary coil is V_{2} =220v

the number of turns in the secondary coil N_{2} =500

the number of turns in the primary coil N_{1} =\frac{V_{1} N_{2} }{V_{2} }

 ⇒V_{1} =\frac{2200*500}{220}=5000v
