Now let's see how you can measure the resistance of a resistor. This is done by color coding over the resistor or you can multimeter to measure resistance. As a beginner you should use color coding. See the following diagrams carefully, you can see that 4-band code, 5--band code and 6-- band code( see next diagram). But we mainly get resistors of 4-band code. You can get a 1/4W resistor for Ps.20 irrespective of the value of its resistance. Due to the aging and other temperature effects, value of a resistor will change. That change is indicated using tolerance.The following figure show how to bend a resistor so that you can insert it in a breadboard. Don't bend too much close to the body of the resistor because it will leads to the breaking of the leads. So bend carefully. Sometimes you have to cut the leads of the resistor by some amount so that it can easily inserted properly. See in the following figure ( resistor in the breadboard). In this case cut the leads of the resistor so that body of resistor just touches the breadboard(see in the PCB).
