Measuring Resistance is difficalt for same people. But,
following six steps will eneble yoou to knew your resistance value. Resistors
are electronic components that oppose the flow of electricity and the
resistance is measured in ohms.
First knowing the value, for larger value kilohms (1,000 ohms) and megohms
(1,000,000 ohms) are used. For example 3,300 ohms equals 3.3 kilohms or just
3.3 k and 1,500,000 ohms equals 1.5 megohms or 1.5 meg.Second knowing about
function of color, Color "bands" are used to indicate the resistance
value with each color signifying a number and these color bands are grouped
closer to one end of the resistor than the other.Third, see the first and
second Color Codes chart, the first two color bands have values of
brown = 1, red = 2, orange = 3 and so on.Next, see the third color band is the multiplier
of the first 2 bands. Here, black is 1, brown is 10, red is 100 and so on.
Putting this in other words, the value of the third band (the multiplier) is
the number 10 raised to the power of the color code. For example, red in the
third band is 10² or 100.Fifth, see the 4th band is the resistor's tolerance and shows how precisely the
resistor was manufactured. Gold = 5%, silver = 10% and no band whatsoever = 20%.Finally,
combine first until 4th color, that’s the value and tolerance resistance of
resistor Knowing the value resistance make void the short circuit and more
safety.
