Question

What is the frequency of rotation of the stationary-bicycle generator's coil?

Options

• \[n=100\,\mathrm{rev/s}\]

• \[n=0.5\,\mathrm{rev/s}\]

• \[n=0.01\,\mathrm{rev/s}\]

• \[n=0.10\,\mathrm{rev/s}\]

Answer 1

The coil rotates at \[n=0.5\,\mathrm{rev/s}\], or half a revolution per second. This is also a rotation frequency of \[0.5\,\mathrm{Hz}\].
