Q 12-07-027NEETJEE MainEasy
A transformer has $500$ turns in the primary and $2500$ in the secondary. With $220$ V ac applied to the primary, the secondary voltage is
Answer: (B) $1100$ V
Concept. $V_s = V_p\dfrac{N_s}{N_p}$.
Step 1. Substitute. $V_s = 220 \times \dfrac{2500}{500} = 1100$ V.
Answer. $1100$ V (Option B).
