Common household appliances are rated at 110 V, but power companies deliver voltage in the kilovolt range and then step the voltage down using transformers to 110 V to be used in homes. You will learn in later chapters that transformers consist of many turns of wire, which warm up as current flows through them, wasting some of the energy that is given off as heat. This sounds inefficient. Why do the power companies transport electric power using this method?
The switch S in Figure 20.27 is closed at t = 0 and the current at a reference time tref 0 is Iref. If the circuit is changed as, described below and the switch is again dosed at t = 0, determine whether the current I at the same time would be greater than, less than, or equal to the original value of Iref. Indicate your answers wilt G. L. or E, respectively. (a) Both the battery voltage and the resistance R are doubled. (b) The inductance L b doubled. (c) The battery voltage . the resistance R, and the inductance L are each doubled. Figure 20.27 A series RL circuit. As the current increases toward its maximum value, the inductor produces an emf that opposes the increasing current.

With the switch in the circuit of Figure 21.18a open, there is no current in R2. There is current in R1, however, and it is measured with the ammeter at the right side of the circuit. If the switch is closed (Fig. 21.18b), there is current in R2. What happens to the reading on the ammeter when the switch is closed? (a) The reading increases. (b) The reading decreases. (c) The reading does not change.
