Which is more accurate when analyzing a circuit (for V, I or R)

[QUOTE="sophiecentaur, post: 6058406, member: 199289"] It all depends ... . Calculations. based on theoretical values are very different in principle from building and measuring some feature of the circuit's performance. Every element in a built circuit will have a tolerance specified, which will indicate what variations to expect in the final circuit if you carry out an analysis for all combinations of component value spread. That could take for ever but you can sometimes shorten the process by knowing what elements will have most effect. For instance, the feedback components will take care of variations in many other parts of the circuit- but it's not something I'd want to do by hand every day. Otoh, measuring the circuit characteristics with a MultiMeter will only tell you what happens for just one set of component values. That may be fine if all you wanted was to know the characteristics of just one particular circuit board but it would not be a good basis for carrying on with production of a large number of circuit boards.
