An AC power generator produces 48 A (rms) at 3,600 V. The voltage is stepped up to 100,000 V by an ideal transformer, and the energy is transmitted through a long-distance power line that has a resistance of 146 Ω. What percentage of the power delivered by the generator is dissipated as heat in the power line? %

A generator supplies 5.0 103 kW of power. The output potential difference is 4500 V before it is stepped up to 510 kV. The electricity travels 400 mi (6.44 105 m) through a transmission line that has a resistance per unit length of 4.1 10-4 /m. (a) What percentage of the power is lost through transmission of the electrical energy along the line? % (b) What percentage of the power would be lost through transmission if the generator's output potential...

A small power plant produces a voltage of 10 V and 100 A. The voltage is stepped up to 120 by a transformer before it is transmitted to a substation. The resistance of the transmission line between the power plant and the substation is 75 ohm. What is the current in the transmissions line from the plant to the substation. please show all work

Please Provide detailed solution. Thank you
An average power of 65 kW is delivered to a distant farm via a transmission line that has a resistance R = 3.00 Ohm. The generator has an rms voltage V_1 = 500 V. A step-up transformer raises the voltage to an rms value V_2 = 10,000 V. Calculate the following: The rms value I_2 of the current on the transmission line The average thermal power (P_thermal) lost on the transmission line. The rms...

1. In class we derived how a transformer can up or downregulate
the voltage in an electrical circuit with an alternating
current.
(a) Use the conservation of energy to deduce how the currents I1
and I2 must be related if you know the ratio of ε1/ε2 (for the
purpose of calculating the power delivered by a circuit ignore any
complications due to the fact that I(t) and ε(t) are
time-varying).
(b) In class I argued that power transmission is more...

A generating station is producing 1.4 x 10^6 W of power that is to be sent to a small town located 6.5 km away. Each of the two wires that comprise the transmission line has a resistance per length of 3.2 x 10^-2/km. (a) Find the power lost in heating the wires if the power is transmitted at 1700 V. (b) A 100:1 step-up transformer is used to raise the voltage before the power is transmitted. How much power is...
