A transformer has 1000 turns in its primary coil and 10000 in its secondary coil.If the primary is connected to a 12000-V alternating voltage,the voltage at the secondary will be
A)12 V.
B)120 V.
C)1200 V.
D)12,000 V.
E)120,000 V.

Question

The voltage in the secondary coil can be found using the transformer equation: $V_s = V_p \times \frac{N_s}{N_p}$, where $V_s$ is the secondary voltage, $V_p$ is the primary voltage, $N_s$ is the number of turns in the secondary coil, and $N_p$ is the number of turns in the primary coil. Substituting the given values: $V_s = 12000 \times \frac{10000}{1000} = 120000$ V.
