RESISTOR

RESISTOR is electronic devices which be used to resist current. In another word it is a circuit component as divider voltage in electronic circuit. In analogical case such as water flow which be resisted by variable valve in order to ensure that the water flow conform with our setting. In Pneumatic system, we also can find the basic concept of resistor operation. In order to get fix pressure in hydrolic/pneumatic we can change and set variable pneumatic. So do resistor work. Suppling current in to component circuit correctly is one of important item should be attentted in electrical system. Because each component must be powered exactly. For example IC need vcc ­+ 5 volt, Circuit supply is 12 volt. So in order to get 5 volt we have to reduce the voltage in to 5 Volt. There is one way to get it such as installing fix resistor before IC.
