Answer

Explanation:

Step1: Recall transformer - voltage ratio formula

The formula for a transformer is $\frac{V_p}{V_s}=\frac{N_p}{N_s}$, where $V_p$ is the primary - voltage, $V_s$ is the secondary - voltage, $N_p$ is the number of primary coils, and $N_s$ is the number of secondary coils.

Step2: Rearrange the formula to solve for $V_s$

We can rewrite the formula as $V_s=\frac{N_s}{N_p}\times V_p$.

Step3: Substitute the given values

Given that $V_p = 6000$ V, $N_p = 50$, and $N_s = 20$. Then $V_s=\frac{20}{50}\times6000$. $V_s = 0.4\times6000=2400$ V.

Answer:

B. 2400 V
