AC Generator & Transformer

Primary side of a transformer is connected to $230\text{ V},\ 50\text{ Hz}$ supply. Turns ratio of primary to secondary winding is $10 : 1$ . Load resistance connected to secondary side is $46\,\Omega$ . The power consumed in it is:

Show answer and solution

Answer: (a)

$V_s = V_p\dfrac{N_s}{N_p} = \dfrac{230}{10} = 23\text{ V}$
$P = \dfrac{V_s^2}{R} = \dfrac{23^2}{46} = 11.5\text{ W}$
So the answer is (a) 11.5 W.
