about its value for a (i) step-up transformer (ii) step-down
transformer?​

Explanation:

The number of turns on the secondary of the transformer is greater than that of the primary, i.e., T2 > T1. Thus the voltage turn ratio of the step-up transformer is 1:2.

Answer:

Turn ratio is the ratio of the number of turns of secondary windings to the number of turns on the primary windings of the transformer.

(i)  Step-up transformer= Ns >Np.

(ii) Step-down transformer=Ns<Np.

Explanation:

  • The turn ratio of a transformer is defined as the ratio of the number of turns on its secondary windings to the number of turns on the primary windings of the transformer.

           T=\frac{N_s}{N_p}     (1)

   Where,

    T=turn ratio of the transformer

    Ns=number of turns in the secondary coil

    Np=number of turns in the primary coil

  • The turn ratio for the step-up transformer is Ns >Np.
  • The turn ratio for the step-down transformer is Ns<Np.
