Question

question #15 using the diagram above, what would the voltage be in the secondary coil of the transformer? 2000 volts 10 volts 5000 volts 200 volts

Explanation:

Step1: Recall transformer - voltage ratio formula

The formula for the voltage - turns relationship in 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 turns in the primary coil, and $N_s$ is the number of turns in the secondary coil.

Step2: Identify given values

We are given that $V_p = 1000$ V, $N_p=50$ turns, and $N_s = 10$ turns.

Step3: Rearrange the formula to solve for $V_s$

From $\frac{V_p}{V_s}=\frac{N_p}{N_s}$, we can cross - multiply to get $V_s=\frac{N_s}{N_p}\times V_p$.

Step4: Substitute values into the formula

$V_s=\frac{10}{50}\times1000$ V.
$V_s = 200$ V.

Answer:

D. 200 volts
