Measuring The Resistance

             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.
