Q:An electrical connection between an electrical circuit or equipment and the earth is called a ?
Voltage in the US is 110-120 volts while in other countries it is 220-240 volts. if you have a 110-120 volt appliance, you need a step-up transformer (110 to 220)before you could use it in a 220 volt power supply.
Q:What does nfpa 70 stand for?
What Does Nfpa Stand For
Q:which of the following electrical equipment cannot convert a.c into d.c?
Hmmm a diode bridge can change ac to dc, but not just a diode. all it does is block current flow one way a converter - as in an inverter? This will convert dc to ac a transformer only works with ac, because it depends on the magnetic flux I dont' even know what a mercury arc rectifier is, but it sounds like it might work
Q:Who can tell me how ski lifts and snow making equipment work?
Your electric drive motors run on high voltage. Three phase 480v. All of your controls and safety systems run on low voltage. Battery powered, 24 or 48 volt. This is so that the lift can operate properly in the event of a power outage that cuts power to the drive. Lifts have backup drives, usually a diesel generator that can supply power to the electric drive motor, or an actual gas or diesel motor that can be coupled to the gearbox and drive the lift itself. Controls are usually a programmable logic control that monitor proper operation of different components of the lift and through a series of relays send power to the drive. Snowmaking is as aforementioned powered by large electric pumps and air compressors. Air and water are pumped usually from a central location and piped around the mountain to hydrants. Here, the snow guns are connected to the air and water. Some types of guns simply blow the water and air to make snow, while some have motors on them. These plug in to electrical pedestals, high voltage, that are located at the hydrant locations. These power large fans that help disperse the water and also control oscillating guns.
Q:Insulators and Conductors questions. Help. 10 Points Each.?
1. In a conductor, electrons transfer easily from atom to atom. In an insulator, it is extremely hard to cause electrons to shift atom to atom. (edit) This means an electrical current cannot flow in an insulator, as electrons must move in a conductor. (end edit). 2. In winter, the air contains less moisture. Therefore static charges will not dissipate as quickly as they will in moist air, and are more easily generated. 3. For the above reason, moving dust particals can easily induce a charge in them, which will be of opposite polarity to the surface. They can be attracted back to the surface. Using a slightly moist cloth can help when dusting in winter. 4. Plastics etc. are electrical insulators. Plastic insulation is very easy to apply to a conductor by extrusion around the conductor, in a plastic extrusion machine. The material is heated to a suitable plastic constituency. Plastic insulations are NOT used in extreme heat or cold situations for conductors. If you live in the US, you will see lots of rubber insulated power leads, as plastics can get more brittle and fracture in cold conditions. Plasticity is the state between solid and liquid, which is where all plastics are worked. In fact, many materials other than plastics can be worked in a plastic state, even metals!
Q:Why can't I find a job?
No one wants to pay you what you are worth.
Q:where can I find a differential +/- 5V power supply ?
McMaster-Carr is a good place for general electrical equipment
Q:what sort of problem do electrical engineers work on?
Q:Dodge problem?
If you didn't have the electrical problems, I'd say it was the transmission. Since you have electrical problems, it's more likely that there is a loose or bad connection between your battery and alternator. Your car is 10 years old, so, presumably, you've changed the battery at least once during that time. Since the industry standard is every 5 years, you might be due for a change! With any luck changing the battery will fix the loose cable connection. Of course, it could be the alternator, too, as well as a bad ground. Use a voltmeter with all the appliances running, to see if you get at least 15 volts; it is normal for the needle to oscillate a tiny bit back and forth. If it's below 15 volts, your alternator may need to be replaced, or, a wire is loose at that end. In some cars, low electrical output can confuse the computer. BE VERY CAREFUL WHEN HANDLING CAR BATTERIES AND OTHER ELECTRICAL EQUIPMENT!!! Good luck!
Q:Can you give me an insight of : Sourcing Heavy Electrical Equipments in India ?
Suggest that you contact the Indian embassy, trade department, they will probably give you a list of suppliers.
