The rising mains are essentially used in electrical distribution system in buildings two storied and above. It is basically used in indoor applications. Nowadays vertical type distribution is normally used as it is more convenient and reliable compared to rising cable system.
A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
This abbreviation comes from the 1950s US Navy electrical shipyards assemblies. It was used to abbreviate what was then called "Circuit Breakers". This is how the "K" crawled in. Today these parts are simply called connectors or headers but the abbreviation stuck since. Many say that it is a mere spelling error, but the fact is that English abbreviations are often misspelled compared to their origin words, for example - OK abbreviates "All Correct".
You can buy what are called Tandem circuit breakers. These only take up one space but allow you to connect 2 individual circuits to it. For example, say you had 4 - Single pole 20 amp breakers taking up 4 spaces. You could buy 2 - 20 amp Tandem circuit breakers and that would give you 2 additional spaces in your electrical panel. Just add up all your amps that your circuits will be pulling at one time to make sure you won't be overloading your electrical panel. One drawback to these Tandem breakers is that they are rough on your wallet. They are pretty expensive compared to regular breakers. Hope this helps
because it can withstand more temperature compared to germanium and relatively cheaper and it is available abundantly in sand where as germanium is rare so Si has advantages than Ge though its conductivity is more compared to Si
No. There are a few reasons why a pneumatic control valve can not be used with hydraulics applications. Firstly, pneumatic seals are incompatible to the chemical properties of hydraulic oils and they do not have the strength to accommodate the high pressures produced by a hydraulic system. Secondly, pneumatic valves are not designed for high pressure operation and the component would get damaged, burst or crack. Finally, the tolerances within pneumatic components would allow by-passing due to the slacker tolerances compared to hydraulic components. By-passing causes all sorts of problems by itself: Over-heating, leaking, internal structure damage of the component.
hydraulic system are self lubricatedthey don't produce much noise when compared to pneumatic system

Wires stretch and sag. Hydraulic fluids transfer force with far smaller losses.
Yes. Though the response time of a pneumatic system is better as compared to hydraulic, power output is higher in latter.
There is more Physics in Mechanical engineering as compared to Electronics engineering.
Well, both of them are related. Large jet liners require hydraulic power to operate the huge flight controls such as ailerons, elevators and rudders. In a conventional aircraft, mechanical linkages attached to the control wheel and rudder pedals are used to operate hydraulic control valves that in turn provide hydraulic fluid to hydraulic actuators that in turn move those heavy flight control surfaces. In a Fly By Wire aircraft, an electrical signal is generated when the same control wheel and rudder pedals are moved which in turn electrically opens or closes the same hydraulic control valves that provide hydraulic pressure to the hydraulic actuators. To summerize, hydraulic power is required in both Fly Bt Wire aircrafts and conventional aircrafts.
it is because pneumatics is more flexible and easy to use rather than hydraulic[ebolton] There is no need to have a reservoir or return piping. The working "fluid", air, is non-toxic and non-flammable. Poster below is correct. Air systems typically have a tank that is the analog of a hydraulic reservoir.[ebolton]*****************Actually there is need for air reservoir in industrial pneumatics systems.Hydraulics can handle more powerful aplications than pneumatics for the same overall dimensions, or can be more compact for the same power.
it could be compared to a stove because the stove provides electrical energy for the making of the food
The electrical resistance in thick wires is less than thin.
Computer engineering is the one that most relates to robotics as compared to electronics and telecommunication and electronics engineering.
Hydraulic power steering is a primitive technology used for decades and has improved a lot with time. Earlier, it did not have any difference in steering response with speed of the car, but the new age of hydraulic power steering are speed sensitive and work better than the older hydraulic power steering.Electric power steering are comparatively new technology with less complicated build and mechanism, takes less space and are more durable. Electric power steering use sensors to sense the car speed and will take care of the different steering response required for different speeds.Some of the main differences are as below:1. Hydraulic Power Steering System is complicated compared with Electric Power Steering2. Hydraulic Power Steering System usually weighs more than Electric Power Steering3. Hydraulic Power Steering uses hydraulic fluids for operation whereas there is no such fluid needed for Electric Power Steering, thus Electric Power Steering needs less maintenance compared to hydraulic power steering.4. Electric Power Steering gives better response at different speeds as compared to Hydraulic Power Steering5. Eclectic Power Steering is less prone to problems and faults and are more durable as compared to Hydraulic power steering.6. Hydraulic power steering extracts power from engine, so it reduces the fuel mileage of the engine. Electric power steering consumes power from battery which is also charged by engine, but it consumes less power compared to Hydraulic power steering. So a car having Electric power steering will give more mileage than one with Hydraulic power steering.Conclusion :Electric Power Steering is better than Hydraulic Power steering.Hope this helps :-)
