The generator at a power plant produces AC at 24,000 V. A transformer steps this
up to 480,000 V for transmission over power lines. If there are 2,000 turns of wire in
the input coil of the transformer, how many turns must there be in the output coil?

    Twenty times as many.
    The voltage ration (2O) equals the turns ratio.
