Question

The primary winding of a transformer has 200 turns, whereas its secondary has 100 turns. The primary is connected to an AC supply of 100 V, 60 Hz. The secondary will have an output of

Professor PC Thomas Classes · Answer

(d) : Given $N_p = 200$, $N_s = 100$, and $V_p = 100$ V. Using the transformer equation $V_s/V_p = N_s/N_p$, we find $V_s = 100 	imes (100/200) = 50$ V. A transformer alters voltage and current but does not change the frequency of the AC supply. Therefore, the frequency remains 60 Hz.
