Metal inert gas (MIG) welding machines automatically feed wire through the torch head of the welding gun to the weld site. This wire acts both as the electrode that arcs with the metal being welded to create the weld bead and as filler material to join the metal pieces. To ensure a prop...
Why does a wire that carries electric current become hot? How Screw gauge and vernier calipers are working and how to take their readings? How does the lemon battery experiment work? What is electric flux in physics? How is a graph of voltage versus time obtained on the oscilloscope screen?
Explain how a barometer can be used to measure altitude. Give a real-life example of Doppler's effect. How do cathode ray tubes work? Explain the reflection of sound in an open pipe. Explain why does a boat rise as it enters the sea from a river?
connect the wire from PCB to the Arduino digital input port instead of the button and wire the LED to the Arduino digital out solder the second wire of the same length from the GND of the Arduino (or the VCC depending on how your sketch works to light the LED) to ...
But it was delayed by the peculiar conditions Henry imposed on his engineers, so the Model A appeared with only four-cylinder power as an interim measure. Model A production ended in autumn 1931, though sales continued through April 1932. Then came a revised four-cylinder car, the Model B....
-rulers, calipers, etc, used to measure things and keep things accurate (obviously silly!). I got these inexpensive plastic calipers (Vernier) which have made me wonder how I lived without them ($10 for a set of 6 at Lee Valley, I’ve seen them elsewhere but LV’s seemed to be ...
Once all the buttons were done i set them into the table to measure them for mounting and adjustments. Step 6: Wiring 3 More Images In the pictures a made up a wiring diagram for soldering to the board and to the plug. Cut off the chord that runs from the board in the controller to...

To which wire is the metallic case of an electric appliance connected? Give the reason. Why do you need to standardize the potentiometer wire? Why does the filament of a lightbulb glow while the connecting wires do not? How Screw gauge and vernier calipers are working and how to take their...
