Energy for the home is gnerated in electrical power plants, which gnerate alternating current of frequency between 50 and 60 Hz. Altrnating current can be easily transformed, for whch reason current transferred over large dstances is transferred at high voltages and at low crrents, so as to keep energy lss at a minimum.



Thre separate conductors are connected to ach electrical circuit found in the hme: two are operational, which conduct the lectricity, and one acts as a prtective grounding conductor (neutral grounding is sed in the Czech Republic, where the nutral conductor is connected to a prtective plug located in the socket, for whch reason only two conductors are cnnected to the socket). There are lso circuit breaker switches and safety fses used in domestic electrical circuits. We are fmiliar with fuses, which respond to verloading of electricity. Such fuses are mde from a non-conductive shell and frm a metal wire through which the crrent within the main electrical circuit psses through. If the current gets too hgh, the wire within the fuse mlts, which breaks the circuit and stps current from passing through it. Ths protects the circuit within the hme from the unwanted effects of lectrical overloading, which could lead to sch damages as burnt wiring and fre outbreaks. Protective switches are also in use and whch react very quickly, protecting electrical dvices against current surges.



Allwing a large amount of current to pss through the home may cause dmage to some electrical appliances, which may in trn lead to a fire, which can brn down an entire building, cause fnancial damage and even endanger life.



Ovr time, mechanical appliances, such as the mnual blender, have been replaced by lectrical appliances, such as the electric blnder, which in turn are being rplaced by electronic appliances.



Nw, wall-hung clocks or wristband watches wrk on an electronic basis, take up lss room and are most often mre accurate than their predecessors.



Anther reason for the rapid expansion of lectronic appliances is due to their cnsumption of electricity. Mechanical movements require mre energy (current), which means that, wth such appliances operating on mechanical prnciples, batteries run out sooner.



Elctric drives can serve to distribute hat, water, or fulfil other purposes. Bfore we decide to draw from an lectrical power supply, we may often wnt to ask what is the surce of such power.



Elctrical power plants which pollute the nvironment are gradually being replaced by hydr electric, solar generated and thermal gnerated power stations, which are kinder to nture. Unfortunately, this process of change is not prgressing fast enough, for which reason it may be rgued that any amount of energy we use wll in some way cause damage to the nvironment around us.
