What is the current in the outlet?

Modern life is closely connected with electricity. We constantly use a large number of all kinds of devices, devices, machines, tools that operate from the mains. And what kind of current in the outlet, not everyone knows. Now let's talk about this.

So, at home it is customary to usehousehold sockets, which have an alternating voltage of 220 volts. As you might guess, an alternating current is used in the outlet not by accident. The fact is that 220 volts is the maximum, that is, the amplitude voltage, which constantly operates in a household outlet. To determine the voltage value, one can use the formula u = Umax * sin (2ωt), where Umax is the maximum voltage, t is the time, and ω is the frequency.

In addition, the home network is single-phase,since it originates in a three-phase alternating current network. In this case, the branching occurs from all conductors, both zero and three-phase. It is worth remembering that between all the phase conductors in a three-phase network, the voltage is 380V, and between the zero conductor and the phase conductor, 220V.
