Electric power passes through a nearby power transformer on its way to your home. The current that enters your home actually receives its power as it passes through the secondary coil of that transformer. Doubling the number of turns in the secondary coil would
A) halve the voltage available at your home.
B) double the frequency (cycles-per-second) of the alternating current entering your home.
C) double the voltage available at your home.
D) halve the frequency (cycles-per-second) of the alternating current entering your home.

Doubling the number of turns in the secondary coil of a transformer increases the voltage by a factor of two, according to the transformer equation $V_p/V_s = N_p/N_s$, where $V$ is voltage and $N$ is the number of turns in the primary (p) and secondary (s) coils.
