The energy is the power multiplied by time. Hence, the energy consumed by the load is b. 5 times the original load resistance. 5 2 E = Pt = This is less energy than the one computed in step c. 1, the load voltage V load is reduced when more customers are added. 1. 2 Assume VS = 100 V and the load resistance R = 1 Ω. Compute the length of the wire that would not result in load voltage reduction by more than 10%. Assume the wire is made of copper and the diameter of its cross section is 3 cm. 673 × 10 −8 Ω-m.

When the power reaches customers’ homes, the voltage is further stepped down to the household level of 100–240 V, depending on the various standards worldwide. 1. The bulk power of the generating plant is transmitted to load centers over long distance lines called transmission lines. The lines that distribute the power within city limits are called distribution lines. There are several other categories such as subtransmission lines, but these are fine distinctions that we should not worry about at this stage.

The invention of the synchronous generator goes back to Hippolyte Pixii (1808–1835), who was the first to build a dynamo. The synchronous machine has a magnetic field circuit mounted on its rotor and is firmly connected to the turbine. The stationary part of the generator, called a stator, has windings wrapped around the core of the stator. When the turbine rotates, the magnetic field moves inside the machine in a circular motion. As explained by Faraday, the relative speed between the stator windings and the magnetic field induces voltage across the stator windings.
