The resistors components that that decrease the amount of conductivity in the path
. They are used to limit current or as a voltage divider to provide a lower voltage than the supplied voltage to a component. And the colored bands on a resistor define the resistance value in ohms.
You will find electrolytic capacitors if you look for components that look like little cans with lead coming from the bottom. The capacitors can range in size from about the size of a resistor to the size of your forearm, though the physical size has little to do with the actual capacitance. The physically large capacitors may be low capacitance, but able to operate at very high voltages. Usually in microfarads, the capacitors' voltages value will be printed on the body of the capacitor.
Resistors and Capacitors have their own useful during the electronic components, the effects of them are different because they are different components, and with same components, because the value, and other features are not the same, so they play different roles in electronic circuits. But after reading this post, you will be clearer about the two electronic components and know how to identify them in simple.
