330R - Carbon Film Resistor 1/4W

Looking for the perfect addition to any electronics hobbyist's arsenal? We have just what you need — our 1/4W Carbon Film Resistor 5%. With its excellent wattage rating of 0.5 Watt and a tolerance of 5%, this carbon film resistor will help revolutionize your project!

A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.

The main function of resistors in a circuit is to control the flow of current to other components. Take an LED (light) for example. If too much current flows through an LED it is destroyed. So a resistor is used to limit the current.

The carbon film resistor explained

The above image shows you the inner workings of a carbon film resistor. As you can see in the image above the more space there is in the carbon film spiral the resistance will be low and when there is less space in the carbon film spiral the resistance will be high.

Color Bands

The above image gives you a visual explanation of how the color bands or color coding on a resistor works. Please keep in mind that on a band resistor, the third color is your multiplier(the number of zeros to add), on a 5-band resistor the 4th color will be your multiplier.
