SOLUTION The high-voltage transmission line can be modeled as a resistor RT . 065 /mile) (220 miles) = 14 The model for the entire system is actually very simple. The system can be modeled by a circuit consisting of the source, the transmission line, and load all connected in a series. This is shown in Fig. 2-15. 25) RT I + RL + − Vs − Fig. 2-15 A model of high-power transmission line and load.

CHAPTER 1 An Introduction to Circuit Analysis 23 Summary In this chapter we have introduced some basic notions that form the foundation of circuit analysis. We have learned that current is the amount of charge that ﬂows per second and that in electrical engineering, by convention, we indicate the direction of positive charge ﬂow in a circuit by a current arrow. We have also learned about voltage and current sources and how to calculate power in a circuit. All of the examples in this chapter have used generic circuit elements.

Since the power is positive, the element absorbs power. On the other hand, suppose that i(t) = −3 A. Then p = (5 V)(−3 A) = −15 watts In this case, the power is negative and the element delivers power. The element is a power supply. Note that a given circuit element can be a power supply or absorb power at different times in the same circuit, since the voltages and currents may vary with time. If the current arrow points in the opposite direction to the +/− terminals of the voltage source, we take the negative of the current when computing the power.
