The primary of an ideal transformer has 100 turns and its secondary has 200 turns. If the input voltage to the primary is 100 V, we can expect the output voltage of the secondary to be
A) 200 V.
B) 50 V.
C) 100 V.
D) none of the given answers.

The output voltage can be calculated 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, and $N_p$ is the number of turns in the primary. Plugging in the given values, $200 V = 100 V \times \frac{200}{100}$, so the correct answer is 200 V.
