Through Hole Resistors

Through-hole resistors are components used to reduce or control electrical currents in electrical circuits. These types of resistors have leads that pass through holes drilled in the circuit board and are soldered into place. They are the most commonly used type of resistor in the electronics industry, and have a wide range of applications and working principles.
