A resistor is a passive electrical component that limits or regulates the flow of electric current in an electronic circuit. Resistors are used in practically all electronic devices, and they come in a wide variety of shapes, sizes, and resistance values.

The most common type of resistor is the carbon film resistor. Carbon film resistors are made by depositing a thin film of carbon onto a ceramic core. The resistance value of the resistor is determined by the thickness of the carbon film.

tors, metal oxide film resistors, and thick film resistors. Wirewound resistors are made by winding a metal wire around a ceramic core. Metal oxide film resistors are made by depositing a thin film of metal oxide onto a ceramic core. Thick film resistors are made by printing a resistive paste onto a ceramic core.

• Limiting current flow: Resistors can be used to limit the current flow in a circuit to prevent damage to other components.
• Dividing voltage: Resistors can be used to divide a voltage into two or more smaller voltages.
• Creating a voltage bias: Resistors can be used to create a voltage bias for active components, such as transistors.
• Terminating transmission lines: Resistors can be used to terminate transmission lines to prevent reflections.
• Creating timing delays: Resistors can be used to create timing delays in circuits.
