We take electricity for granted one second and gawk at its power the next. More than two and a half centuries have passed sinceBenjamin Franklinand others proved lightning was a form of electricity, but it's still hard not to flinch when a particularly violent flash lights up the horizon. ...
These heavy-duty batteries are mainly used for toys, flashlights, and portable radios. Many automatic hand sanitizer dispensers require the use of these 1.5V batteries. Perfect for heavy-duty applications where batteries require frequent use, you can be sure that your device is operating with safe...
In this example, when the input signal goes low, the output from the555 timergoes HIGH for a certain period of time before going back to LOW. You could for example use it to turn on the lights on your porch for 2 minutes every time an IR sensor detects that there is someone present....
Inside your house, the electric charge moves in a large circuit, which is composed of many smaller circuits. One end of the circuit, the hot wire, leads to the power plant. The other end, called the neutral wire, leads to the ground. Because the hot wire connects to a high energy ...
Now that we've identified the circuit breaker, we can safely reset it. Important: To prevent shock, wear safety glasses, make sure your hands are dry, stand to the side, and stand on a dry surface when resetting a circuit breaker. Turn off all the lights and unplug everything in the ...
In new-construction homes, it is common for builders to install recessed lights directly into the ceiling joists. This means the fixtures are attached from above and require access from the attic space to remove them. However, many homes do not have attic access or have limited access, making...
A small light on this circuit lights up when it's complete, also. The Cold Heat tool also has some electronic components beyond basic wiring. A small circuit board is at the end opposite the tip. This circuit board has two diodes, several resistors and a 14-pin integrated circuit. When ...

LEDs use a much lower amount of energy compared to all types, not just because they are more cost-efficient in terms of power consumption but also because there aren’t as many circuit boards required for installation. LED lights last up to 25 times longer than incandescent lights. Businesses...
