Chapter 21, Problem 12(choose chapter or problem)
The references for the voltage and current at the terminal of a circuit element are as shown in Fig. 1.6(d).The numerical values for and i are 40 V and 10 A. a) Calculate the power at the terminals and state whether the power is being absorbed or delivered by the element in the box. b) Given that the current is due to electron flow, state whether the electrons are entering or leaving terminal 2. c) Do the electrons gain or lose energy as they pass through the element in the box?
