Complete the textWhat's the difference between electricity and electronics?If you've
read about electricity, you'll know it's a kind of energy—a very
versatile kind of energy that we can make in all sorts of ways and use in many
more. Electricity is all about making пустоcurrents energy flow around a
circuit so that it will drive something like an electric motor or a heating
element, powering пустоelectromagnetic such as electric cars, kettles, toasters, and
lamps. Generally, electrical appliances need a great deal of energy to make
them work so they use quite large (and often quite dangerous) electric пустоappliances . The 2500-watt heating element inside an electric kettle operates on a
current of about 10 amps. By contrast, electronic components use currents
likely to be measured in fractions of пустоmilliamps (which are thousandths of amps).
In other words, a typical electric appliance is likely to be using currents
tens, hundreds, or thousands of times bigger than a typical electronic one.
Electronics
is a much more subtle kind of electricity in which tiny electric currents (and,
in theory, single electrons) are carefully directed around much more complex
circuits to process пустоsignals (such as those that carry radio and television
programs) or store and process information. Think of something like a microwave
oven and it's easy to see the difference between ordinary electricity and
electronics. In a microwave, electricity provides the power that generates пустоhigh‑energy waves that cook your food; electronics controls the electrical
circuit that does the cooking.
