| THE CIRCUITS - THE "IDEAL" CIRCUIT | ||
In designing circuits, it is often necessary to know how the voltages and currents of the individual circuit elements – the batteries, light bulbs, resistors and so forth - are all related. For this purpose, the concept of ‘ideal’ sources of voltage and current was created. As a rule, ideal sources and other ideal circuit elements are required by engineers to obtain models that are realistic enough to begin initial design and analysis of how a new circuit will function. |
