Question:

A 460-loop circular armature coil with a diameter of 7.0 cm rotates at 170 rev/s in a uniform magnetic field of strength 0.35 T. What is the RMS voltage output of the generator? What would you do to the rotation frequency in order to double the RMS voltage output?

Voltage:

The electromagnetic force, which describes the potential difference of an electric charge from the initial point to the final point, is defined as the voltage. It can also be said that the voltage is the source of power that pushes the electrons in a loop.

Electrons are motivated to power circuits through voltage sources, which can be clearly seen in batteries and other everyday items. Generators can come in the form of nuclear, coal, natural gas, hydroelectric, and wind power to generate voltage. In this lesson, learn about energy conversion, voltage, voltage sources, and examples of these things in everyday life, including batteries and generators.
