The generator at a power plant produces AC at 24,000 V. A transformer steps this up to 345,000 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?

  • Physics - ,

    For transformers, the turns ratio equals the voltage ratio.

    2000/n = 24,000/345,000

    Solve for n.
