Feed drops to zero volts when light switch is turned on back to 120 volts when turned off feeds fluorescent lights?

voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.

Can you mix two hot wires and neutral in same shut-off switch?
Yes two "hot" wires and a neutral can enter into a switch box. This is done on occasions where a three wire enters a switch box, drops off one circuit for the lighting and the other "hot" wire carries on to feed a receptacle circuit.
What are the disadvantages of helical antenna?
Efficiency drops with added turns. Maximum efficiency is about 80% with a 3-4 turn helical and drops to about 60% at 12 turns.
What does a resistor do in an electric circuit?
Limits current flow and drops voltage.
What effect does increasing the timing capacitor have on the frequency out of an Astable 555 timer?
frequency drops
What is total voltage in a series circuits?
In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.
Why does the RPM of 1995 Mitsubishi lancer GLi drops when lights are turned on?
It requires more power, RPM goes down when demand for power is higher especially if lights are on or air conditioning
Are neon lights similar to fluorescent lights How?
Sort of but also not.A lot of "neon" lights actually are fluorescent lights, they just have a coating that gives them their color. If the light looks the same color when it's turned off as it does when it's turned on, or if you can see regions where the color changes in a single tube (not counting spots that are just painted opaque black), then it's really just a fluorescent light with a coating. If the tube is just clear glass when it's turned off, it's probably a "neon" light.Both neon lights and fluorescent lights are gas-discharge lamps; they work by ionizing a gas so that it releases when it drops back to the ground state. The main difference is that in a neon light, you perceive the light emitted directly (the light coming from the gas is the color you see) and in a fluorescent light, the light emitted by the gas (usually mercury vapor) is a different frequency than what you see (usually in the UV region). These photons are captured by a fluorescent material lining the inside of the tube, which then emits photons of a different (lower) frequency in the visible spectrum.If you can get your hands on spectroscope or a diffraction grating (you can sometimes use the silver side of a CD for this), it's interesting to look at a fluorescent light with one. The light that you perceive as white (or nearly so) is really several distinct colors which you can see as bright bands, usually at least one in the red, one in the green, and one in the blue ... there may be others as well.You see the same thing if you look at a neon tube with the diffraction grating, but the colors are actually the frequencies directly emitted by the ionized gas."Neon" lights that contain actual neon are a reddish-orange color. The term is also used for tubes that work the same way but contain other gases; these give different colors. Here are pictures of some Geissler tubes containing different gases: https://en.wikipedia.org/wiki/Gas-discharge_lamp
Why would a computer reboot when any appliance like vacuum cleaner or dishwasher is turned on?
The electrical circuit voltage drops when an appliance is turned on. (Lights dim, etc.) A new circuit is needed or you could purchase a UPS (Uninterrupted Power Supply) to act as a buffer and prevent the voltage drop. JR
What causes hunting on an x reg focus 1.8 petrol engine?
If you mean hunting at idle, the problem is caused by the idle speed being set too high or the idle switch is not properly adjusted. When the throttle is closed as indicated by the idle switch the fuel is cut off by the fuel cut solenoid until the engine speed drops below a preset speed. If the engine speed is higher than that speed and the idle switch is closed there is no fuel for the engine, thus the engine speed drops. When it drops below the preset speed the fuel is turned on and the engine speed goes back up.
Can you use fluorescent bulbs outdoor?
Can??? Sure, you'd just need to come up with a waterproof enclosure.But the problem is, many fluorescent fixtures don't work well when the temperature drops. Yes you can use fluorescent fixtures outside, they should be approved for the purpose and make sure they have 0 degree rated ballast for cold weather starting. The new electronic type ballast work in cold weather with no problems.
Why the color of the tubelight in the roadside restarunt were green?
Assumptions: (1) By "tubelight", you mean a fluorescent outdoor lighting fixture. (2) By "green", you mean that the color of the lamps were not normally green, but appeared to have turned green. Answer: Fluorescent lamps have a well-known problem, in that they do not work well if temperature drops below 50 degrees F. At temperatures below 50 degrees F, they may not "start" (refuse to light up initially), and if they do, the color may be shifted.

Have crolla 1984 on cng battery is ok charging 13.5 volts but even drops if head lights are used battery drops?
your alternator is going bad
Will fluorescent lights create more algae in an aquarium than incandescent bulbs?
Hey there, Nah it wont cause algae. If ur tank does get algae its probably because of a plant that u have in there that uve added. But that's easily fixed by adding a few drops of algae clear bought from ur aquarium.Hope that helps. Catch! :oD
How do you stop the gas on the turn off switch from leaking polaris scrambler 500?
the place where you turn the gas off on my fourwheeler keeps leaking out do l need a new gas switch? it keeps leaking when l turn the gas off there be drops of gas comeing out when the gas is turned off l have scrambler 2002 500

What would be the effect on the circuit if the starter was taken out after the fluorescent lamp is started?
A; fluorescent lamps needs 500 v to start once started the voltage drops to ~90 v the starter perform the kicking to get to 500 volts without it it will not start so taking it out after it started that is when it is not longer needed
