Electric Current And Its Transport

Cables and wires are used to carry current from the electrical panel to your home’s different rooms. The main difference between these two conductors is that an electric cable comprises several electric wires in a sheath. Before choosing your cable protector outdoor and wires, find out everything you need to know about how they work.

There are two types of current: direct and alternating.

Direct Current

Electrons move continuously from one point to another in a closed circuit. This current type is used for devices using little electrical power, for recharging portable equipment (laptops, mobile phones, etc.). Still, it is also used for the high voltage lines to reduce current losses or when the electrical networks between 2 countries are different.

Alternating Current

The current is said to be alternating when the electrons circulate alternately in one direction and then in the other at regular intervals. This is the case with the current distributed by your electricity supplier in your home network. The single-phase current is the most used for the general public. It uses two conductors: phase and neutral.

Electric Current Measurements: intensity, voltage, and power

Current Intensity

It is a number that defines the flow, that is to say, the flow of movement of electrons in a conductor such as a wire. Intensity is measured in amperes (A). The greater the need for electrical power, the thicker the conductor must be to maximize the flow, in other words, the flow of current supplied by the electrons to the requesting equipment.


It is measured in volts (V). The voltage delivered in domestic installations is 230 volts.

Electric Power

Its unit is the watt (W). It represents the electric voltage product to the terminals of which an appliance is connected (hob, lamp, etc.) and the intensity of the electric current flowing through it.

Understanding Electrical Cables And Wires

The more your home contains electrical equipment requiring a high voltage, the more power to be delivered by your meter will have to be necessary. In domestic installations, it is calculated in kilowatt (kW). It is with this measure that you dimension your electricity subscription. Your meter calculates your energy consumption in kilowatt-hours (kWh).
