Please check my answer. Anyput is great.
Name the three main sections of an electric grid. Generation Transmission Distribution Explain the advantages of AC power over DC. AC can change direction. DC doesn't let the current to flow the opposite direction. AC is preferred over DC for large scale generation and transmission over long distances. AC electricity from a single source can be easily subdivided into many circuits that operate at different voltages and currents. This is accomplished through the use of transformers. There is up versus down transformers. AC allows the transmission of electricity at low current and high voltages. This is very important because high currents cause high losses of energy as heat. It's easy to generate AC electricity. AC electricity is generated in power plants by rotating powerful magnetic fields in the presence of giant coils of wire. Name a power generation technology that produces DC current. Solar Photovoltaic The electric produced by PY panels is DC. Explain how transmission system losses can be decreases in an electric grid. Transmitting electricity at high voltage will reduce the energy lost to resistance. This will depend on the flow of current, length of transmission line, and conductors. Thus: this is why we prefer AC over DC. AC allows the transmission of electricity at low current and high voltages. This is very important, because high currents cause high losses of energy as heat. A 100 MW wind farm has a 45% capacity factor. How much power is generated by this farm on average? 100 MW * -.45 = 45 MWExplanation / Answer
Yes your answers are correct. It will be better if you you write "electricity produced" and not "electric produced".
Also you can add- i) AC generator with commutator produces DC. ii) Rectifier is used to convert AC to DC. iii) All battery power supply gives DC always.
In Ac vs DC you can add-
i) AC genertion is efficient than DC. ii) AC generation is cheaper than DC. iii) Magnitude of AC can be easily made low without loss of excess of energy using choke coil.
Rest parts are good.
