Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

A major hazard involved with water heaters is that they operate under whatever pressure the serving water utility supplies. Water stays liquid at temperatures higher than the normal boiling point of 212F (100C). If the high-temperature limit control failed to operate for whatever reason, should a pipe burst or a faucet be opened, the pressure would instantly drop to normal atmospheric pressure, causing the superheated water to turn into ______________ that could result in ______________. To prevent this from happening, water heaters are equipped with pressure/temperature relief valves.

can you answer these questions on solar thermal collector experiment using the following bullet points. Why does correct positioning and weather affect the results obtained? Why it worked/failed. In your opinion, is Solar Thermal a useful technology for the UK? Avoid giving a binary answer and try to think of all variations of solar thermal technology and all regions of the UK. How would you modify the technology to become better/more efficient and more appropriate for the UK? If you were given the chance to do the experiment again, how would you do it and why? The answers to these questions should be supported by mindful arguments. This should occupy, at least, two pages of the report.
The electromagnet shown in the Fig. below is to be used to lift an iron slab of mass M=150 kg. The surface roughness of the iron is such that when the iron and the electromagnet are in contact, there is a minimum air gap of 0.2 mm in each leg. The electromagnet has infinite permeability and the crosssectional area Ac is 25 cm2. The number of turns of N-turn winding is 350 and the winding coil resistance is 3 Ω. Calculate the minimum coil voltage which must be used to lift the iron slab against the force of gravity. Neglect the reluctance of the iron.(Hint: Gravitational acceleration constant is 9.8 m/s2)
You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
