The resistor color code is the scheme of coloured bands painted on a resistor to show its value, used because the parts are too small to print numbers on. Reading left to right, the first bands are significant digits, the next band is a power-of-ten multiplier and the last band is the tolerance. For a 4-band part the value is (10 × digit1 + digit2) × 10^multiplier ohms; 5- and 6-band parts add a third significant digit for tighter precision (and, on 6-band parts, a temperature-coefficient band). Each colour maps to a fixed number: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, grey 8, white 9, with gold and silver serving as ×0.1 and ×0.01 multipliers or ±5% and ±10% tolerances.
As a worked example, the classic brown-black-red-gold band pattern reads as digits 1 and 0, a ×100 multiplier and ±5% tolerance: (10 + 0) × 100 = 1,000 Ω, i.e. a 1 kΩ ±5% resistor whose true value lies anywhere from 950 Ω to 1,050 Ω. Decode any part by selecting the colour of each band from the drop-downs and the calculator returns the nominal resistance, the tolerance and the guaranteed value range.
Switch to reverse (encode) mode to go the other way: type a target resistance and the tool rounds it to the nearest value the digit bands can express, chooses the multiplier to match, and lists the band colours you would read off a real resistor of that value — handy when you have a schematic value and need to find or verify the physical part on your bench.
Fanontaniana matetika
Ahoana no fiasan'ny lokon'ny rezistant?
The first two (or three) bands give the significant digits, the next is a ×10ⁿ multiplier and the last is the tolerance. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%.
Inona no dikan'ny "fifampiraharahana"?
Ny fisiana ara-daharampehintany ary ara-daharanjarahasin'ilay kaominina dia 45.5000° ary 1.0500° amin'ny soratra desimaly.
Ahoana no fomba ahazoana ny feon-kira amin'ny fomba miverina?
Ny fiteny dia mizara ho sokajy telo: ny fiteny fototra izay ahitana ny teny fototra rehetra, ny fiteny fototra izay ahitana ny teny fototra tokana, ary ny fiteny fototra izay ahitana ny teny fototra maro.
Inona no fahasamihafana eo amin'ny 4-, 5- ary 6- band resistors?
Ny 4-band resistor dia manana soratra roa; ny 5-band dia mampiditra soratra fahatelo ho an'ny fiheverana henjana kokoa toy ny ±1%; ary ny 6-band dia mampiditra soratra farany amin'ny tahan'ny hafanana mampiseho ny fiovan'ny sanda isaky ny degre. Ny soratra maro dia midika matetika fa singa tsara kokoa.
Iza amin'ireo farany amin'ny resistor no hamaky voalohany?
Manomboka amin'ny fefy akaiky indrindra amin'ny farany ary vakio mankany amin'ny fefy fankasitrahana, izay volamena na volafotsy matetika ary mizara kely amin'ny sisa. Raha volamena na volafotsy no mipetraka amin'ny farany iray, dia io no fefy fankasitrahana, ka vakio avy amin'ny farany mifanohitra.
Inona no dikan'ny volamena sy ny volafotsy?
In the multiplier position gold means ×0.1 and silver means ×0.01, giving sub-ohm values. In the tolerance position gold means ±5% and silver means ±10% — the two most common everyday tolerances.
Nahoana no tsy mifanaraka amin'ny fehezan-dalàna ny fihenjanako?
The bands give a nominal value plus a tolerance window. A ±5% 1 kΩ resistor may legitimately measure anywhere from 950 Ω to 1,050 Ω, and temperature and age can shift it further, so a small mismatch on a multimeter is completely normal.
