In stcp-up transformer, relation between number of turns in primary $\left(N_{P}\right)$ and number of turns in secondary $\left(N_{S}\right)$ coils is

  • Correct answer
    A
    $N_{S}$ is greater than $N_{P}$
  • B
    $N_{P}$ is greater than $N_{S}$
  • C
    $N_{S}$ is equal to $N_{P}$
  • D
    $N_{P}=2 N_{S}$

Solution

In step-up transformer, number of turns in secondary coil is greater than the number of turns in the jxrimary coil. 1.e. $\quad N_{g}>N_{\mathrm{P}}$

Hence, the correct answer is option: 'A'.
