### Resistor

1. 1. Resistor<br /> Pencil as <br />
2. 2. INTRODUCTION<br /> A resistor is widely used for resistance of an electric current. For example, you’re a driving a car, while driving a red light is showed for you to stop. If there would be no red light and still your are not stopping, there would be a possibility that an accident will occur like there is no control.<br />
3. 3. A resistor is an electronic component that resists the flow of current in an electronic circuit. Resistors are often made out of chunks of carbon or thin films of carbon or other resistive materials. They can also be made of wires wound around a cylinder. The common resistor is a two-wire package with a fixed resistance measured in ohms; however, different types of resistors are adjustable by the circuit designer or the user<br /> As we all know electricity is an element involve and attach in our daily lives. It is our need for without it, we will not be able to perform our daily activities. <br />But also, on the other hand electricity has also its bad effects to humans and to the surroundings.<br />
4. 4. Statement of the problem<br />1. What is the element that the 2b pencil has that can resist the <br /> flow of electric current?<br /> <br />2. Why does a 2b pencil resist electric current?<br />3. What is the effect of connecting directly the LED and the battery clip?<br />4. What is the effect of gliding the battery clip to the drawn shape on your paper till’ get near of the other clip in which attach to LED?<br />5. What’s so important about resistor?<br />
5. 5. Hypotheses<br />1. There is a connection between the 2b pencil and the darkness of the drawn shape on the paper to rate how it resist electric current.<br />2. There is a connection of the element present on the pencil and the rate of resistance of the pencil. <br />3. There is relation of the battery and the battery clip, for this things is the one that serves the flow of the electric current<br />
