A resister is a passive component. It introduces resistance. Resistance as the property of a material which opposes the flow of current. Science the resistors have no polarity; they can be connected in the circuit either direction.

The main purpose of resistance used in the electronic circuit is
Limit the flow of current
Provide load
Produce a desired voltage drop
Control gain
Fix time constants.
