Fifteen megawatts of electricity is to be transmitted over a power line of resistance 3 ohms. ( I don't know how to solve D and E)

a) If the electricity is generated at 10,000 V and is to be transmitted at 200,000 V, what should be the ratio of turns of the transformer?
b) At what current will the power be transmitted? c) What percentage of the original power will be lost in the line because of resistive heating?
d) If you didn’t use the transformer, but transmitted the energy at 10,000V instead, what current would flow through the wire?
e) In this case, what percentage of the original power would be lost in the line because of resistive heating?

    A typical overhead power line is bare wire at a high potential relative to ground. A local line receives power at 3300 V with respect to the ground; the delivered voltage is slightly less, due to resistance loss in the wire. The wire is 10 km long, carries a current of 60 A, and has a resistance (made small to limit power loss) of 2.5 Ω. 1) Approximately how much power is lost due to the resistance of the wire?...

    In most circuits the resistance of wires is negligible. Over long distances, however, it can become significant. Imagine a 160 km long cable from the power plant. It is 0.9 cm diameter and made of aluminum, with resistivity of 2.65x10m. It carries current to light your 60 W light bulb which is connected to your 120 V outlet. a) What is the resistance of the cable from your power plant? R- b) How much current goes through your light bulb?...
