Electrical Devices vs Electronic Devices—What’s the difference?
网页2016年6月6日 · Electronic Devices. In contrast, electronic devices do much more. Instead of just converting electrical energy into light, heat, or motion, electronic devices are designed to manipulate the electrical current in ways that adds meaningful information to the current. For example, an electronic toaster uses the same heating elements, springs, and ...
Understanding the IEC 62368-1 standard for electronic equipment
网页2021年12月20日 · IEC 62368-1 now refers to a varistor as a possible ignition source, thus requiring additional tests. The varistor overload test (the Annex G.8 portion of the standard) is a stress test that progressively steps up the power in the varistor. The test uses an AC source to apply twice the equipment’s voltage rating through a resistor to the ...
Throwback Tech: 20 Old Products Modern Technology Replaced
网页2013年12月2日 · 12. Rounded TV screens. Older TVs operated from photons being fired from a photon gun in the back of the TV, hitting the screen in such a way to produce color pictures. The screens were rounded to provide ample distance from the electron gun (cathode) and the screen. Newer flatscreen models do not use this technology.

What It’s Worth: Vacuum tubes worth more than the tube tester
网页2011年5月2日 · This was one of the first tubes available for consumer radios. A working early Aeriotron WD-11 can easily sell for up to $130 in today's collectors market. If it's not working it still is a valuable display item to a collector and a $75 to $80 selling price is not uncommon. In the early 1950s the transistor appeared.
Brushless dc motor block diagram - Electronic Products
网页2014年5月14日 · Brushless dc motor block diagram. A brushless DC (BLDC) electric motor is likened to a motor with brushes, but turned “inside-out.”. A BLDC motor has a rotor with permanent magnets and the stator contains the windings. Older motors with brushes rely on the brushes to conduct electrical current between moving parts.
Why doesn’t the US use 220V like everyone else in the world?
网页2016年9月30日 · First is the idea that the United States is the only country in the world to use the 120V 60Hz standard. The fact of the matter is that there are many other countries that primarily use 120V. To this end, there is no “everyone else in the world”. Some countries use 240V, some 230V, others 220V, and so on.
