Artaigil mu chòd dath an aghaidh-aghaidh
Tha Resistor 'S e aon phàirt de chuairt dealain a bhios ag obair gus smachd a chumail air àireamh nan sruthan dealain. San fharsaingeachd, tha dà sheòrsa resistors ann, is iad sin resistors coil uèir agus resistors gualain. Mar as trice, bithear a' cleachdadh resistors rolla uèir san obair-lann, air an dèanamh le bhith a' pasgadh uèir mhìn air uachdar an tiùba inslitheach. Mar as trice, bithear a' cleachdadh resistors gualain ann an cuairtean dealanach, siolandair, agus tha uèirichean aig gach ceann. Tha luach an aghaidh resistor gualain air a chur an cèill ann an còd dath agus air a thaisbeanadh air uachdar an resistor.
Gheibhear luach strì an aghaidh-resistor le bhith a’ mìneachadh còd dath an aghaidh-resistor. Gus seo a thuigsinn, thoir sùil an toiseach air a’ chlàr a leanas, agus an uairsin sgrùd an eisimpleir de dhuilgheadas gus luach strì an aghaidh-resistor a dhearbhadh.
Eisimpleir de dhuilgheadas 1:
The resistor resistance value on the figure is …
fuasgladh:
The first two colors represent the first two numbers of the resistance value, the third color represents the tenth power used to multiply, and the fourth color represents the tolerance of deviation.
The first color = red = 2
The second color = orange = 3
The third color = brown = 101 = 10
The fourth color = gold = 5%
The resistor value is 230 Ω with a deviation of 5% x 230 Ω = 11.5 Ω. If there is a change in temperature, the minimum resistance is 230 11 – 11.5 Ω = 218.5 Ω and the maximum resistance is 230 Ω + 11.5 Ω = 241.5 Ω.
Eisimpleir de dhuilgheadas 2:
What is the value of the resistor resistance in the figure?
fuasgladh:
The first color = brown = 1
The second color = black = 0
The third color = blue = 106 = 1000,000
The fourth color = gold = 5%
The resistor value is 10,000,000 .000 with a deviation of 5% x 10,000,000 Ω = 500,000 Ω. If there is a change in temperature, the minimum obstacle is 10,000,000 500 – 500,000 Ω = 9,500,000 Ω and the maximum obstacle is 10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
