Q:explain the difference between an insulator and a conductor
The main difference between conductor and insulator is that a conductor conducts electricity or heat well, whereas an insulator conducts electricity or heat poorly.
Q:Do electrical equipment work with AC or does the voltage get converted to DC before working anything!! for exampe, if i connect something such as a light bulb directly to an AC outlet, would it work or would it get blown out, why do somethings get blown when using AC
AC mean alternating current where the positive and negative switch continuously. DC means direct current which there is just one positive and one negative. If you connect a lightbulb to DC or AC it would work since the flow of electricity will work in either direction to power the light. however it all depends what you're using in terms of voltage, watts, etc. if you take an automotive bulb and plugged it into a house out let it would blow. Different components work only for direct current and some only work with alternating current.
Q:google chrome, will I have a faster connection to be able to watch movies etc. like netflix?
Q:I have a piece of electrical equipment that uses a 12v DC in that i want to replace with a battery, as it currently uses a wall charger with an AC converter. How would i go about doing this for cheap? making it myself wouldn't be out of the question, all i need is a guide. The 12v pack must also be as small as possible, as it is powering a portable device.
I would find what signal would tell the amp to go into low power mode, and force that into the high power state. One possibility is the subwoofer amps are powered only by the AC charger, in which case you could re-wire their power so they get it from the built in battery. As for actual external power, you can use a couple appropriate RC packs, or a 12V SLA type battery.
Q:01 impala trunk equipment?I have an 01 impala and theres some equipment in the trunk on the drivers side. what is it for?it is some electrical equipment. with wires plugged to itits not the amplifierits on the drivers side tire well
On Star receiver/ broadcaster GPS tracking for crash assistance.
Q:2)Please do include the details as to why does spark devlop wn connection at one end is loose. 3)How the +ve electrode retains itz polarity though it accepts the electrons continuously, in a closed circuit.
1) For laymen understanding, electrical grounding is a protection of your house against lightning, instead burning your house or someone inside your house gets fried. In your appliances, electrical grounding protects you from getting electrical shock in case one of the electrical wire touches the metal body of your appliance. Now on electronic grounding, it is a protection of a certain circuitry from getting damaged by an electrical charge from your body in case you touch it. 2) Electrical wire connection is like a water pipe connection. Electrical current passes through the wire while water current passes through the pipes. If there is a loose connection of a certain electrical wire, or loose pipe connections on your water pipes; The loose pipe connections will produce leaks while the loose electrical connections will produce sparks. 3) It always retain its polarity always. Just like magnets, it retains its polarity, north and south. Electricity is based on magnetism. Law of nature.
Q:I just moved to a house in Vancouver, WA, and am wondering what companies can ship/move a large storage container (like PODs) from Houston, TX to here in WA. I will be doing it within the next month or two, and need a general estimate on how much it is going to be (I can figure that out, just need some websites or company names)
PODs, U-Haul has something similar but smaller and ABF freight has a small POD to a you fill the entire trailer.
Q:if my electrical equipment has a fuse; does that not mean it's protected?is it just the power grid that goes down?
A solar flare doesn't destroy electrical equipment. A strong coronal mass ejection can interfere with the transmission of power by inducing a geomagnetic current in power lines which is contrary to the current being transmitted, producing effects similar to a short circuit. This can do physical damage to transformers, but a more likely result is that it would trip safety equipment to detect short circuits, which would shut down the line. This is what happened in Quebec in the 1989 blackout. So, yes, it is just the power grid that goes down, unless you take the perverse step of directly connecting your electrical equipment to miles of elevated wire to serve as an antenna over which the current can be induced, and delete the fuses.
Q:Basically a reptile shop is selling some dangerous equipmet which I have brought. These include a un-ballasted fluorecent bulb unit (some home made unit using a plug a terminal and 2 end caps) (the vivarium looks burnt) (I wonder why :P) and they sold us a second hand starter unit (ballasted) which stank of smoke and had a 13 amp fuse however should have had a max 3 amp fuse. They are very un-knowledgeable about reptiles and the fuse to the starter unit looked burnt on the ends. I'm just worked about the safety of others who buy their equipment from there as I know for a fact most of it's dangerous. They sold me a 30w starter unit for a 15w bulb which I brought from them at the same time, any ideas who to contact about this unsafe store (I'm in the uk) thanks. :)
Trading standards, local council. Local newspaper maybe if you are really unhappy about it they will for sure close the place down
Q:I cannot see that a electrode would be useful in a generator, is there a way?
According to Wikipedia: An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). There is an example of an electrode used in generators, and all industrial/commercial electrical systems. It is called a grounding electrode. It is a metallic rod that is driven deep in to the dirt, to establish a contact with the background Earth voltage. Is the dirt a nonmetallic part of the circuit? Well, dirt often does contain metals in it, but it isn't dominantly metal, so it still is considered non-metallic. And we normally hope that the dirt isn't part of the circuit, but there is a chance that it can become part of the circuit, and that is generally why grounding electrodes are installed. The grounding electrode doesn't really play an active role in the operation of any of the electrical equipment. It is more of a safety feature, as a JUST IN CASE the insulation on the live wire fails. Suppose the live wire insulation fails, and the live wire contacts the metal structure of a device (that isn't intended to play an electrical role), and you as a human victim touch that metal structure. You are also standing on the ground, and the natural path of electric current from the metal structure to the ground is through your body. Unless of course, a better path is established in advance. And that is what a grounding electrode, and the rest of the grounding system does. It establishes electrical continuity with all metals that aren't intended to be electrically involved, so that any failure of the live wire will trip the circuit breaker before there is a chance that the human gets injured.
