Resistors are electronic components in circuits. They are used to limit the electric current flow through the circuit. Therefore, these components are very important to regulate the electric current. There are three main types of film resistors named as metal film resistors, carbon film resistors, and metal oxide resistors. The big advantage of carbon composition resistors is their ability to withstand high energy pulses. When current flows through the resistor, the entire carbon composition body conducts the energy. The wirewound resistor, for example, has a much smaller volume of wire to conduct current.
