An 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....
However, DC electricity has a few disadvantages. For example, DC cannot be easily changed to multiple voltage levels using transformers, making long-distance power transmission more complex. In addition, at lower voltages, DC power can be more harmful to people, causing burns and tissue damage. ...
One example of DC power is a standard USB charging device, where the voltage remains steady, and the current follows one direction — from positive to negative. What is AC electricity? The “A” in AC stands for alternating because the flow of current switches direction (unlike in DC ...
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...

Taking the analogy of a beer mug: active power is the liquid beer, reactive power is the head of foam and apparent power is the full glass. This chapter explains the mathematical relationship between “useable electricity” and “wasted electricity”. ...
