The potentiometer is an electrical component that is used to control or in adjusting electrical signals. It is a three terminals pots resistor and an adjustable knob in the center. When varying or tuning the knob, the potentiometer tends to increase or reduce its resistance depending on the tuning. It is used in varying electrical …
SMD resistance which means surface mounted technology resistors is resistance in microchips that are mounted on a circuit board. Is quite different from the ordinary resistors which have their color codes on their body for identifications. Instead, SMD resistors have their value written on their body. These figures on their body are used in calculating …
