... the path with lower resistance. Related End-of-Chapter Exercises: 21 and 24. In a calculation like that in Step 2, a common error is to forget to invert when applying Equation 18.8, stating the answer incorrectly as . Checking units can prevent this error. Also, a rule of thumb is that the equivalen ...

... Example: A two-speed fan. One way a multiple-speed ventilation fan for a car can be designed is to put resistors in series with the fan motor. The resistors reduce the current through the motor and make it run more slowly. Suppose the current in the motor is 5.0 A when it is connected directly acro ...

Network analysis (electrical circuits)
A network, in the context of electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, every component in the network. There are many different techniques for calculating these values. However, for the most part, the applied technique assumes that the components of the network are all linear.The methods described in this article are only applicable to linear network analysis, except where explicitly stated.
