A Resistors is used to create a known voltage to current ratio in an electric circuits. If the current in a circuit is known, then a Resistors can be used to create a known potential difference proportional to that current. On the contrary, if the potential difference between two points in a circuit is known, a Resistors can be used to create a known current proportional to that difference.
Types of Resistors:
There are two major types of resistor used in Electronics.
1- Fixed resistors mostly are carbon film and metal film resistors fixed resistors.
2- Variable resistors are also called Potentiometers or Rheostats and allow the resistance of
the device to be altered by hand.[adsense]
