The goal is to determine the magnitude and direction of one or more circuit variables, and the final task is to verify that the proposed solution is indeed correct. Usually, the engineer first identifies what is known and the principles that will be used to determine the unknown variable. 6-1. Generally, the problem statement is given. 6-1. First, we describe the situation and the assumptions. We also record or review the circuit model that is provided. Second, we state the goals and requirements, and we Problem State the problem.

The voltage of an ideal voltage source is given to be a specified function, say v(t). The current is determined by the rest of the circuit. The current of an ideal current source is given to be a specified function, say i(t). The voltage is determined by the rest of the circuit. An ideal source is a voltage or a current generator independent of the current through the voltage source or the voltage across the current source. Engineers frequently face a trade-off when selecting a model for a device.

5 i(t) + – v(t) Independent Sources Some devices are intended to supply energy to a circuit. These devices are called sources. Sources are categorized as being one of two types: voltage sources and current sources. 5-1a shows the symbol that is used to represent a voltage source.

An independent voltage source provides a specified voltage independent of the current through it and is independent of any other circuit variable.
