You are given a transformer that has 800 turns on its primary coil and 64 turns on its secondary coil. A voltage of 220 V is applied to the primary coil.
What is the output voltage?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 17.6 V
Using the transformer equation,
$\frac{V_p}{V_s}=\frac{N_p}{N_s}$
$⇒V_s=\frac{V_pV_s}{N_p}=\frac{220}{12.5}=17.6V$
