Answer 2

Answer:

220 volt DC is applied to the  primary coil of a transformer  having 100 turns, the  output voltage if the secondary  coil has 200 turns the voltage in the secondary coil is 440v

​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 $V_{1} =220v$

the number of turns in the primary coil $N_{1} =100$

the number of turns in the secondary coil $N_{2} =200$

the voltage in the secondary coil is $V_{2 } =\frac{N_{2}*V_{1} }{N_{1} }$

⇒$V_{1} =\frac{200*220}{100}=440v$
