Question

The turns ratio of a transformer is 15 and the primary AC voltage is 9 V. What is the secondary voltage of the coil?

• A. 6 V
• B. 0.6 V
• C. 1.2 V
• D. 18 V

Answer 1

The correct option is B

0.6 V

Given: Turns ratio = 15 and $V_p$ = 9 V, $V_s$ = ?

We know that, turn ratio = $\frac{V_p}{V_s}$
So, V_s = $\frac{V_p}{\text{Turn ratio}}$
i.e. V_s = $\frac{9}{15}$ = 0.6 V
