q21

please sir solve these 2 questions, thanks alot

question 1

A string of suspension insulators consists of three units. The capacitance between each link pin and earth is one-sixth of the self-capacitance of each unit. If the maximum voltage per unit is not to exceed 35 kV, determine the maximum voltage that the string can withstand. Also calculate the string efficiency. [84-7 kV; 80-67%]

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.

How does IoT play a role in optimizing energy consumption in smart homes? Provide an example.

1. Electrical explosions directly into the face of a person working on or near energizedelectrical equipment can and will cause serious injury or death. OSHA laws and NFPA70E have strict safety requirements for working on electrical equipment. The basicrules are to turn off the power before working on the equipment and to wear the propertype of nonflammable clothing. To further provide safety for the worker, the NationalElectrical Code has a requirement pertaining to arc-flash hazard warning. This requirement is found in of the NEC.
