Answer 1

Answer #1

use,
P = V*I
100*10^6 = 288*10^3*I
I = 347.2 A

power loss = I^2R
843*10^3 = (347.2)^2*R
R = 6.993 ohm
= 7.00 ohm

Answer: 7.00 ohm

PG&E needs to send 100MW to Davis over transmission lines that are many miles long--so long that the resistance is not completely negligible (let's say 0.001?). Given that the product VI needs to be 100MW, PG&E could send this power at low voltage and high current, or at high voltage and low current. If you use as the power dissipated in the lines, it seems like high voltage is bad--it leads to a lot of power wasted in the transmission...

Question 7 1 pts High voltages are used for long-distance electrical power transmission because more voltage means more power. high voltage prevents people from stealing the electricity. wires are better conductors at high voltages. the low currents allowed by high voltage means less power lost as heat in the wire. Water can be boiled by placing it in vacuum, because slow-moving molecules get pushed out of the liquid due to the pressure of the liquid. oxygen bubbles are pulled out...
