DC and AC electricityAn introduction to DC and AC electricity. The text includes conceptual theory, mathematical equations, examples and detailed solutions. Many of the circuits presented can be assembled in the laboratory so that experimental values can be compared with calculated results....
Before explaining the meaning of AC power source, let’s firstly know what AC power is. AC power, which stands for alternating current, is a standard format of electricity that is commonly used in many household and commercial devices. It is characterized by its ability to continuously reverse...
Animation: What's the difference between DC and AC electricity? Suppose you have to vacuum a room. Direct current is a bit like working from one side to the other in a straight line; alternating current is like going back and forth on the spot. Both get the job done, albeit in ...

AC and DC Voltage MeasurementElectricity is very hard to imagine because we can not see if a voltage is present or if a current is flowing. If we want water to flow out of a pipe we need some water pressure which is achieved with a water pump. In electricity, our flow is the current...
First of all, in order to provide a reliable source of DC electricity to a device, the AC voltage will be stepped down by transformers. Secondly, rectifiers will take AC electricity from a source (such as mains power) and convert that energy into DC electricity. Last, a filter will remove...
