It raises the voltage of the output of the main generator to the level of the grid transmission lines. The actual values depend on the design of the plant and grid system. In the UK the generator output would typically be about 23 kV and the grid line at 400 kV. Very high voltages make transmission of power more economical because the current is correspondingly reduced.

iron is collected from blast furnace by drilling the taphole.Taphole is a hole drill and plug after cycle of time located in blast furnace bottom.

There are many ways. FIRST: short the terminals to ensure it is not charged. Many of the digital meters today also have a capacitance check setting, simply use that setting. It not only checks for faults, but also will give you a reading of the capacitance value itself. For most non-electrolytic capacitors a quick check (definately bad vs. maybe good) can be done with an analog VOM. Use the highest resistance scale to measure across the terminals. When first connected there should be a short needle jump that slowly drops back to infinity. Reverse the leads and do it again, should have the same effect. Any resistance highter than infinity indicates a shorted capacitor. Lack of needle jump may indicate an open capacitor (or one of very little capacitance). Electrolytics can also be checked with a VOM, but polarity must be observed, and the drop back to infinity may take a very long time. Alternatively, for electrolytics and larger capacitors is to charge them with a low voltage source (e.g. 9V battery) and measure with multimeter to see if they hold the charge.

The function of a light bulb in an electric circuit is that it turns electrical energy into light.

Coefficient of Linear thermal expansion (CLTE) = Alpha

Alpha=(change in length)/(original length*change in temp)

- Aluminium has good strength to weight ratio so can's can be made thinner (saving money as less material is used) yet still have the required strength.

- Aluminium has a very low density, it is a light metal.

- Aluminium is sufficiently resistant to corrosion.

- Aluminium is cheaper.

- Aluminium is 100 % recyclable.

In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres.

A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron.

A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks

Step up transformers are used to increase voltage.

Step down transformers are used to decrease voltage, these are the most common. The can on the power pole is a step down, a doorbell also uses a step down transformer.

Thermoplastics can be resoftened and remoulded several times,thermosetting can be heated and moulded only once into an irriversible shape.=)

Technical competency is the knowledge and skill to perform the activities within an occupation consistently and over time. This isÊfor a successful accomplishment of a business, job, or a task.Ê

Carbon content in dead mild steel is betweet 0.05% & 0.15% .

The corrosion rate of a metal is a function of many factors like:

-fluid to which the metal is exposed (chemical composition, concentration..)

-temperature

-flow velocity

-time of exposure

so it's not possibile to give a simple answer

Actually an isolation transformer may be physically the same as a Step up/Step Down transformer. The main difference is in the way they are used.

Another difference is that in a normal transformer there will be capacitance between the 2 windings, between the windings and core, between the core and shell, etc. These capacitances bring in high frequency noise from outside, which will be transmitted in the secondary circuit. So [in an isolation transformer] wires are connected between each component, (not direct contact, but with insulation present). This permits a leakage current and eliminates unnecessary capacitance. I could make a start to answer this question. Isolation transformer: is a transformer with two separate windings, the primary and the secondary. There is an electrical isolation between the primary and the secondary. Nearly any type of transformer with two non-connected windings could be considered an "isolation" transformer, in that it electrically isolates the primary voltage from the secondary voltage. There are also transformers with one winding (called auto-transformers) and connections for input and output. If the input is low voltage and the output a higher, then you can say it is a STEP-UP transformer. If the input is high and the output is low, then you can say it is a STEP-DOWN. This type of transformer can not by used where safety is a large factor.

oil is used in industrial hydraulic system because

With the use of steam power, factories could be built near natural resources and where the work force was. Factories started to grow all over England and then spread to the rest of the world. Cities became more populated because the factories offered a lot of jobs. Work in the factory was more reliable than work in the fields due to the fact that farming was dependent on the weather and crops often failed. The steam engine could now make machines in the factories produce materials much faster. By the early 1800's there were hundreds of steampowered machines in the factories. Steam ran the machines in textile mills and other types offactories. In the 1820's lighter and simpler steam engines were made that could be used in small mills and stores and not just large factories.

Bright mild steel is an alloy. It is usually used to make hammer heads and shears, and it has a smooth, but tough surface.

Mild steel is a mild piece of steel.

The answer above is wrong, Mild steel is made from Iron and Carbon.

The answer above is wrong, mild steel is steel that is mild...
