The resistor is a component from the circuit reject the current flow of electricity.
It has two terminals where electricity must pass, and is designed to drop the voltage current that flows from one terminal to another
The resistor is primarily used to create and maintain a secure stream of known in the electrical components.

The resistance measured in ohms, following Ohm's law. This law States that electrical resistance equal to the drop in voltage terminals of the resistor divided by current is applied.

A high ohm rating showed high resistance against the flow. These ratings can be written in a number of different ways – for example, 81R represents 81 ohm, while 81K represents 81,000 ohm.
