Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current.

The no load output voltage typically is only slightly greater than the specified voltage.

Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.

Input: AC 100-127 Output: DC 12V

The motar which can be used 24 hours countinuosly . by which the motor quality remains same is called CONTINUOS MOTOR . The motar which can only be used used for several hours ,namely 2 hours, 4hours, 6 hours depending upon the design of manufacturer is called INTERMITTENT MOTOR.

1. To prevent the buildup of static electricity

2. For safety-a voltage short will blow a fuse or trip a breaker. If hot AC gets to

a metal cabinet that is not grounded, the the cabinet will be "hot" and if you

get between "hot" and ground you could be shocked and possible death.

Others can add more I'm sure.

("Earthing" is another term for "grounding" in electrical wiring.)

Front of motor there is a little indent could say something like b15dy it will be if your standing in front of the car look on the left hand side down about 6 inches

the voltage regulator can be found on the back of alternator,probably the brushes worn if giving you troble

But hopefully you wont have to change it, because it involves removing an axle, jacking up the engine after disconnecting a motor mount, a real difficult knuckle-buster job

A split ring is a name for a ring of spring steel that is made like two turns of a regular spring wound very closely. Usually they are large and used to hold keys together, so they are commonly thought of as key rings.

There is also a smaller version of this used in jewelry to attach chains and pendants.

I'm more familiar with boat propellers but I don't think this can be answered as it stands. You would need to know various factors, such as aircraft resistance, which would be influenced by factors such as aircraft shape and attitude (and hence drag), air temperature, and air pressure. Colder air and lower air pressure would lower air viscosity, which would in turn lower aircraft drag. But the propeller requires a certain air viscosity to function at its greatest efficiency, so you'd need to take that into account. You would also need to know the propeller pitch - the forward movement the propeller travels during a revolution

MWe and MWt are units for measuring the output of a power plant. MWe means megawatts of electrical output, and MWt means megawatts of thermal output. For example, a nuclear power plant might use a fission reactor to generate heat (thermal output) which creates steam to drive a turbine to generate electricity (electrical output). A reactor that generates 200 MWt (50 MWe), and another reactor that generates 800 MWt (200 MWe).

Hot resistance is your total resistance you can have with out exceeding your wattage limit

Type 1A STP or Cat 5 UTP.

The resistance is equally proportionate to "r" in the case that it is above 1. Assuming "r" is greater than 1, the resistance is 4/3 multiplied by omega (the equal proportionate value for mass times ohms).

If "r" is less than or equal to 1, there is no resistance.

The question is not clear can you go into discuss question and explain exactly what you want to do I'm sure I can help

A BUSHING IS A DEVICE USED TO CARRY CURRENT AT HIGH POTENTIALS THROUGH GROUNDED BARRIERS. EXAMPLE: A TRANSFORMER TANKVARIOUS BUSHINGS AVAILABLE ARE, # OIL IMPREGNATED PAPER(OIP) BUSHING # RESIN IMPREGNATED PAPER(RIP) BUSHING

To prevent wire corrosion. Most phone wire is copper, and it is stripped and exposed to air at many points along its path from the telephone company central office to your phone. Also, breaks in insulation could expose small parts of it to water or soil. Any of these will allow the wire to corrode, and the usual methods of corrosion are that copper in the wire is converted to copper oxide or copper carbonate. Both of those happen as a chemical reaction where copper atoms act as positively charged ions to combine with negatively charged oxygen or carbonate ions in water or dirt. A wire with a positive charge will actually draw the negatively charged ions to the wire and will greatly accelerate corrosion. A negative charge will repel the corrosive ions and will slow the corrosion.

A negative charge will cause some copper to be lost due to a process called electro-deplating (reverse of electroplating), but the rate of copper loss is much less than would be caused by copper corrosion with a positive charge.

The phone company power supply acts like a giant battery. They ground the positive site of the supply so that any part of the system has a voltage that is zero or negative, so the whole system resists corrosion better and lasts longer.

Short circuit is the case when electricity, instead of travel through the design circuit path, jump across an unintended low resistance path and bypass the design circuit.
A short circuit is a path for an electric current to travel through where there is very little resistance. This path is often, but not always, through a wire connected directly to a ground, and is often, but not always, unintentional.

Surging in gasturbine means that the pressure at the delivery end of the gas turbine compressor becomes very high (as a result of reduced flow at the compressor outlet). When this happens, the compressor pressure at the delivery end increases as the flow decreases upto an extent after which the pressure does not increase and there is a flow reversal. This flow reversal releases the sudden pressure that developed on account of reduced flow. The flow reversal is accomplanied with a loud noise and tremendous vibration. Surging affects the whole machine and if it is of high magnitude, the gas turbine can be ripped apart. Anti-surge devices (Bleed valves) are installed which do not allow the flow to reduce even on low speeds and keep a certain air flow from the compressor during times of low air requirement (startup and shutdown) Surging in gasturbine means that the pressure at the delivery end of the gas turbine compressor becomes very high (as a result of reduced flow at the compressor outlet).

There are schematics available on the web for about $30 plus shipping and handling.

In my experience, the zero sequence of transformers is not calculated, it is directly tested following ANSII/IEEE guidlines for Z1no, Z2no, and Z1ns tests (for three phase, three winding transformers).

Rough estimations of zero sequence impedance can be determined based on the positive sequence and core form of the transformer. A Shell type core will have a zero sequence of ~100% the positive sequence because the flux stays in the core / follows the same path as it does for positive sequence currents. For a core type, the zero sequence will be ~80-90% typically, because the flux must travel outside the core. This is for three winding transformer.

if you use a uncharged capacitor most likely your car battery will drain much faster using a uncarged capaciter will mess up your amp good power source is needed for your amp to give its maximum potential for deeper bass and no dimming
