1 Search for "CRBT resistance inquirer" directly from Baidu, and then select an online application from the options that appear.
2 According to the actual color of the resistance color ring, click the color options corresponding to the first paragraph, the second paragraph and the third paragraph in turn in the inquirer. At the same time, the resistance value and error will be displayed on the "resistance value" small panel on the right.
3 If there is another resistance to query, you can click the reset button, and then you can re-select the color ring color to query the resistance value.
If there is no computer and network, we can calculate its resistance according to the color ring table. Now take the resistance of the "brown, orange, red and silver" color ring as an example. First of all, we need to remember the color circle table: brown 1, red 2, orange 3, yellow 4, green 5, blue 6, purple 7, gray 8, white 9, black 0, gold and silver represent errors, the first two color circles represent one digit, the power of Theory of Three Represents 10, and the fourth represents errors. Gold represents 5% error and silver represents 10% error.
5 According to the resistance color circle table, it can be concluded that brown is 1, orange is 3, and red is 2, that is,13x100 =1300 ohm. The error is 10%, which we confirmed by online inquirers is the same.
