a. What current (in kA) is needed to transmit 130 MW of power at a voltage of 29.0 kV?   b. Find the power loss (in MW) in a 2.00 Ω transmission line.   c. What percent loss does this represent? (only need part C)

A power transmission line is used to transmit 100 kW of power at a voltage of 10 kV with a loss of 1 kW. If the voltage is increased to 200 kV, what is power loss to transmit the same amount of power?

Define electrical power.Lus An electric heating coil of resistance R is immersed in 1 kg of water at 20 °C. The coil is connected in series with a resistor Y across a 240 V mains supply. The temperature of the water rises to the boiling point in 10 minutes. When Y is disconnected, the time taken for the 1 kg of water at the same temperature to boil is reduced to 6 minutes. Neglecting all heat losses, calculate the resistance R, of Y. | Specific heat capacity of water = 4200 J kg' K"] [7 ma State and exnlain th
