What is the difference between alternating voltage and direct voltage?

When working with electrical machines or installations, you are dealing with alternating voltage and direct voltage. The difference between alternating voltage and direct voltage is that in case of alternating voltage the current continuously changes direction and that for direct voltage it always goes into the same direction. But how exactly does that work? And what should you take account of? In this article, our specialist explains about alternating voltage and direct voltage.

What is alternating voltage?

In case of alternating voltage electrons go from the plus pole to the minus pole and from the minus pole to the plus pole. The current thus continuously alternates its direction. The number of times that this happens within one second, is called the frequency. In Europe the current alternates it direction 50 times per second and thus the frequency is 50 Hertz. The Dutch energy net is based on alternating voltage and so an outlet socket also functions on the basis of alternating voltage. 
AC voltage

What is direct voltage?

For direct voltage electrons go only from the plus pole to the minus pole; the current thus always goes into the same direction. Most electric appliances and installations work on the basis of direct voltage - but outlet sockets only function on the basis of alternating voltage. In general, this is no problem, because the conversion from alternating voltage to direct voltage is relatively easy. This is often done by means of the battery or adapter of a device.

Vice versa, the conversion from direct voltage to alternating voltage is not easy. In addition, this cause a lot of energy loss.
