The 8000-turn primary of a transformer is connected to a 50-kV transmission line and the secondary has 19 turns.What is the voltage output of this transformer?
A)21 MV
B)119 V
C)110 V
D)21 kV
E)220 V

Question

Quizplus · Accepted Answer

The voltage output of the transformer can be calculated using the formula: $V_s = \frac{N_s}{N_p} \times V_p$, where $V_s$ is the secondary voltage, $N_s$ is the number of turns in the secondary coil, $N_p$ is the number of turns in the primary coil, and $V_p$ is the primary voltage. Plugging in the given values: $V_s = \frac{19}{8000} \times 50000V = 118.75V$, which rounds to approximately 119 V.
