Electric current

The current which flows along wires consists of moving electrons. In other words, the flow of moving electrons is the form of the electric current. What can we say about the electron?  We consider the electron to be a minute particle having an electric charge. This charge is negative. As these minute charges travel along a wire, that wire carries an electric current.

In addition to traveling through solids, the electric current can flow through liquids as well and even through gases. In both cases it produces some most important effects to meet industrial requirements. Some liquids such as melted metals, for example, conduct current without any change to themselves. Others, called electrolytes, change greatly when the current passes through them.

The reader certainly remembers that a negatively charged electron moves to the positive end of the wire. It had been supposed to move in the wrong way, from the positive end of the circuit to the negative, long before the electrons were discovered. In fact, when a wire is carrying a current from left to right, the electrons in it are really flowing from right to left.

When the electrons are flowing in one direction only, the current in the wire is direct. The simplest source of power for direct currents is a battery. A battery pushes the electrons in the same direction all the time.

The alternating current flows first in one direction and then in the opposite one. The alternating current used for power and lighting purposes goes through 50 cycles in one second.

One of the great advantages of alternating current is the ease with which power at low voltage can be changed into an almost similar amount of power at high voltage and vice versa.

In fact, at least 90 per cent of electric energy to be generated at present is alternating current. It finds a wide application for lighting, heating, industrial and other purposes.

 

Пояснения к тексту:

in addition to – кроме того, к тому же

as well – также, тоже

in other words – другими словами

to meet requirements – удовлетворять нужды, отвечать требованиям

for example – например

in fact – фактически, на самом деле

in one second – в секунду

vice versa – наоборот

at least – по крайней мере

 

IX. Переведите следующие технические термины и словосочетания:

 

electric current

effects of the electric current

direct current

source of power

alternating current

low (high) voltage

electric charge

(electric) circuit

negative charge

moving electrons
