An Electrical Resistor is a passive two-terminal component commonly used in electrical circuits to introduce resistance to the flow of electric current. It is designed to limit the flow of electrical current and dissipate electrical energy in the form of heat. The primary function of an electrical resistor is to resist the flow of electrical current.

Attributes:
• Used to limit the current to protect sensitive components
• Used as voltage dividers to provide a specific voltage reference or reduce voltage levels
• Modify electrical signals by attenuating or amplifying them.

Applications:
An Electrical Resistor is used in heavy machinery with electric motors, resistors are used for soft-starting and speed control to prevent sudden surges in current and mechanical stress.
