But if you are relying on precise values, you might be disappointed. If you need general-purpose resistors that are within a few percent of their marked values, these kits are probably fine. Later, he had more of a planned smoke release. He did some experiments with hot air to determine the temperature coefficient and the power handling capability of the resistors. We liked the test jig he built to do the four-wire resistance measurements more easily. That doesn’t sound like much, but if you bought them for their 1% tolerance, a 1.4% error is way off the mark. Some of the resistors were within 1% of the marked value, but others were as far out as 1.4%. The Longrunner resistors, however, did not fall in range. The sample size was a little small to draw a solid conclusion, but it does look like the resistor were well within their advertised tolerance. The Elegoo kit measured the expected resistance value within the tolerance band. They look the same because they are both coated with tin, but the magnet tells the difference. For example, a magnet revealed that one brand of resistor had iron leads which are not as conductive as copper leads. He starts with two resistor kits and examines them quite closely. In a recent video, he checks out some Amazon-supplied 1% resistors to find out how good they are. Are these inexpensive parts really any good? likes to find out. But today, you can order parts inexpensively and get them on your doorstep in a day or, sometimes, even less. These often came from manufacturing runs where a company bought 10,000 components and made 8,000 products. Some places sold surplus parts, which could be cheap.

TV repair components were another option, but, again, big bucks. But you might not have many choices, and the price would be on the high side. Sure, you could get some things at Radio Shack. Decades ago, electronic components were not as easy to acquire as they are today.
