testing a light bulb? - a multimeter on the power socket. To test a bulb you look at it and if it shines...
No, that would not be proper. The contact point of a light bulb socket has no need of any coating. A light bulb socket that is difficult to turn a bulb in will benefit from some light oil on the bulb threads prior to installing. Dielectric grease will harden, and is meant to insulate and protect electrical junctions from exposure and vibration.
A light coating of silicone lubricant, available as a spray, on the bulb threads, will lubricate the bulb and socket, and be electrically safe, and will make future removal much easier. Only a LIGHT coating, or short spurt of silicone, wiped over the bulb base, should be used.
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
An A19 shaped globular bulb with an E26 base is the standard bulb that has been used in homes for the last few decades.For a chart see related links below.The A19 refers to the type of and size of the bulb base and socket. There are a myriad of different bulb shapes, but they need an A19 base to fit an A19 socket (standard light socket).
A bad light socket, corrosion inside of light socket, poor ground connection, wire disconnected/damaged, wrong type of bulb was used or bulb was installed incorrectly.
You're looking at 130v light bulbs? Well...the answer is "nowhere." A 130v light bulb has a heavier-duty filament in it than a 120v bulb does, so the bulb will last longer. Put it in a regular socket and it will work fine.
where was the first light bulb used
yes argon is used for light bulb and it is not reactive
a light bulb as the ones used in lamps. lights by fine filament inside the sealed vacuum bulb. one side of the filament connects to the bottom raised portion. the other end of filament connects to the silver screw in part. when the light bulb is screwed all the way down, the bottom of the bulb hits the slightly raised flap at the bottom of the socket. pos.+. and the side of socket is in contact with the side of bulb. Neg.-.put on switch and and electricity flows through the filament, you have light.
Replace bulb - they are double filamented with smaller used fro stop light larger for tailight Check light socket for corrosion, power and ground
The gas in a light bulb is Argon
