AC Generators
Alternating currents can be generated using devices which are known as alternators. Apart from these, there are many circuits that are able to produce alternating voltages and currents.
One of the most basic ways to produce an AC voltage or current is by using a single-coil AC generator. The generator consists of two-pole magnets and a single loop of wire which has a rectangular shape. For supplying AC, the following three wires are used:
- Hotwire for power transmission.
- The neutral wire is connected to the earth, this wire provides a return path for the current in the hot wire.
- The third wire is connected to the earth and is linked to the metallic parts to avoid electric shock hazards.
Alternating Current
Alternating Current and Direct Current are the two types of electricity based on the direction of the voltage and current. In households, we use mostly Alternating Current as the grids are designed to provide alternating current only. But in the case of power storage, DC is used. Alternating currents vary with time so does their voltage.
All the appliances in a common household are wired to work with these types of currents and voltage sources. To understand the workings of these devices in real life, it becomes essential to understand the concepts behind alternating current (AC). Let’s look at these concepts in detail.
