Radios, amplifiers, televisions,
tape recorders, computers, and many others
electronic devices operate by
electricity consumption. Shorter
speaking, the current source is an integral part of wireless
devices.
That's why your
the first workshop on the road dating from the Radio
Engineering and will be thesis is toka.Ty sources, I hope you
know that the current separated by a constant
and variable. With a constant stream of media
electric charges
(Electrons) in a conductor, such as
segment of wire or filament bulbs, included an electrical
circuit, move all time in one direction. At variable
same current, the electrons in a conductor, or in the
same filament bulbs move alternately in one direction and then
in another direction.
In respect elektroosveti network, the current changes
its direction with
at 50 gerts.Gerts
(Hz) is the main unit Measured frequency
1Hz-kollebanie one full second.
Electric current of tension, measured in volts (V), and
strength, measured in amperes (A). Measure these
electrical parameters of the voltmeter and
ammeter.
CATERING
For experiments that illustrate the principle of action and
properties of semiconductor diodes and transistors to power
your first electronic devices that require galvanic cells
(batteries): 4.5 B, and 9B and best of all take 5V from his
home computers. In the future we Tell about how build your own
power supply unit (PSU).
