Why does a light bulb light up immediately after you turn on a switch even if the switch was a long way from the bulb? Why does the filament of a lightbulb glow while the connecting wires do not? Household circuits are always wired so that the electrical devices are connected in parallel...
Explain why the voltage and resistance will change depending on the length of the material. Why is there always a difference between the experimentally calculated error for resistance, and the actual components tolerance value? Why should the wires connecting the resistances and the bridge need to b...
Also onDecember 20 (but in 1951), the first radioactive electricity hit the wires from the Experimental Breeder Reactor I, at the Argonne National Laboratory in Idaho. On that day, a string of four light bulbs lit up, using the world’s first nuclear-generated electricity. The lab’s dire...
If you have insulated or bare aluminum wires, there are a few things to remember to ensure you receive the best price at your scrap yard. Insulated aluminum wire is often used to replace copper wire in many instances as a cheaper and easier solution. While it is not quite as good a con...
So, there it is. The 3-phase 4-pole induction motor. A simple device actually. Steel. Copper. Windings. No friction from moving parts except the bearings the rotor turns on. It’s the alternating current that really makes the magic happen…. the movement of those elect...
It can range depending on what you can handle. I use about 2-3 teaspoons. Susan 03.10.14 at 2:20 pm I’m just curious, everything i’ve read says do it in the morning. I don’t really have much time in the morning. Are there any drawbacks for doing this before bed?
The First Church, is most recognizable by its all granite Neo-classical extension; a large ornate domed structure on Mass. Ave that can seat up to 3,900 people. 1876: FIRST Christmas Card Published in the US In 1875 Louis Prang, a prominent lithographer, published the first American ...
Have you ever wondered why Easter can fall in either March or April, unlike Christmas which is always on December 25th? For example, last year Easter was on April 9th, while this year it falls on March 31st. The reason behind the shifting date of Easter is quite interesting. Easter is ...
The Christmas lights used to decorate the Christmas trees have a parallel connection at one time the connection of each light is made in series which represented a problem when one of the small bulbs was damaged. To solve this problem it is necessary to a...
Why does the filament of a lightbulb glow while the connecting wires do not? Why do we require modulation? Why there is no intensity distribution due to single wave? Why is the tungsten filament in the electron gun folded? Why is the filament of a bulb twisted? Why isn't it straight?
