A high voltage direct current (HVDC) electricity transmission system comprises a voltage source in series with a transmission line, which can be represented by a resistance Rs. The system provides energy to a city, which can be represented be a single load resistance, RL- In all of the questions below, give numeric answers correct to 3 significant figures and include units where required. a. It Rg = 30.7 12, for what value of Ry, is the power delivered to the load maximised? Number Units b. If it is decided that the system should be at least 95% efficient, what is the minumum load resistance that can be permitted? Number Units
