AC Single Phase Generators: Gensets that are useful for powering small appliances

A voltage supplied by a battery or another DC source has a certain polarity and remains constant. We looked at that in our discussion of DC and we looked at battery connected to something and we saw that it had a positive polarity and a negative polarity and it remained constant, it did not change. Alternating current AC varies in polarity and amplitude.

The voltage which changes polarity at regular interval of time is known as the alternating voltage. The one complete cycle of an alternating quantity consists two half cycles. And the direction of a half cycle changes after every particular interval of time. The machine which generates the alternating voltage is known as the alternator. In small AC generators, the coil rotates between the magnetic field, whereas in large ac generator the magnetic field rotates around the coil because of some economical consideration.

AC Single Phase Generators: Gensets that are useful for powering small appliances

Latest Articles in "Industry News". Alternating current AC is an electric current that periodically reverses its direction, in contrast to direct current DC which only flows in a single direction which cannot change sporadically. Most students of electrical engineering and related subjects begin their studies by learning about direct current DC. This is because most of the digital electronics these students will build will use DC. However, it is important to understand alternating currents AC and its concepts too, because it has many useful properties and use cases.
