volt

In volt (abbreviated with V), the electrical voltage (formula sign U) is given. To put it simply, the tension indicates how quickly the electrons move, i.e. how much energy is necessary to move an electrical load within an electrical field. A socket in Germany and Europe provides an output voltage of 230 volt alternating current. In the United States, on the other hand, the voltage is usually only 120 volts.

With the electrical voltage, it must be taken into account that all electrical devices can only be used with the specified operating voltage. If this is not met, the lamp can be damaged if the number is too high or not put into operation if the volt value is too low. For this reason, the 230 volt voltage does not need the 230 volt voltage coming from the socket, transformers to transform them into another volt value.

In addition, the voltage in volt also influences the power in watts and the current in amperes, since the formula is: watt = volt X ampere. These three sizes therefore belong together in a way and, for example, you can calculate when the fuse flies out, which of course needs to be prevented.
