Question 121:
easy50. The primary winding of a transformer has 500 turns whereas its secondary has 5000 turns. The primary is connected to an A.C. supply 20 V, 50 Hz. The secondary will have an output of (1997)
Output voltage $V_s = V_p \left(\frac{N_s}{N_p}\right) = 20 \times \left(\frac{5000}{500}\right) = 200 V$.
The frequency of an alternating current does not change when passing through a transformer.
Therefore, the output will be $200 V, 50 Hz$.
