A power plant transmits 106 [W] of power through wires that have a resistance R = 1 Ω. 

a) If the power is transmitted at 105 [V], what is the current? 

b) In this case, how much power is lost to heat?

c) What percent of the available power is this?

d) If the power is transmitted at 103 [V], what is the current?

e) In this case, how much power is lost to heat?

f) What percent of the available power is this?
