# What is the use of a 0 ohm resistor?

This format allows it to be placed on the circuit board using the same automated equipment used to place other resistors, instead of requiring a separate machine to install a jumper or other wire. Zero-ohm resistors may be packaged like cylindrical resistors, or like surface-mount resistors.

### What is the purpose of a resistor in a circuit?

The main function of resistors in a circuit is to control the flow of current to other components. Take an LED (light) for example. If too much current flows through an LED it is destroyed. So a resistor is used to limit the current.
• #### What do the bands on a resistor mean?

A gold tolerance band is 5% tolerance, silver is 10%, and no band at all would mean a 20% tolerance. For example: A 220 Ω resistor has a silver tolerance band. Tolerance = value of resistor x value of tolerance band = 220 Ω x 10% = 22 Ω
• #### What is the function of resistance in an electrical circuit?

A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
• #### What is the purpose of the wire in the circuit?

A light bulb in a series circuit is used to determine whether or not electricity is flowing. The purpose of the wires in a series circuit is to allow the electricity to flow from one device to the next. Wire is used to carry the flow of electrons. Metal wire is a very good conductor.
