Question

ifif number of turns of primary and secondary coil of a transformer are 250 and 50 respectively find input voltage of transformer if output voltage is 25v​

Answer 1

Answer:

125V

Explanation:

Given Data:

Np=250

Ns=50

Vo=25V

 Find :  $V_{inp}$ =?

Solution:

              $\frac{Vout}{Vinp}$=      $\frac{Ns}{Np}$

    25/ $V_{inp}$    =  50/250

   25/  $V_{inp}$    =  1/5

    25 × 5      = $V_{inp}$

              $V_{inp}$ =125V
