On the most basic electronic components is hindering the flow of current. Two of the most basic parameters to measure the resistor is resistance and power. Used to express the blocking effect of resistance resistor current, ohm. In addition to the basic unit, as well as kilohms and megohm. Used to indicate the maximum power current resistor can bear, Watt said, 1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W etc, more than this maximum value, it will burn out resistor.

According to the materials of different cement resistors, resistor (low production cost, large power, thermal noise, the resistance is not accurate enough, work is not stable), carbon film resistors, metal film resistors (small volume, stable operation, low noise, high precision) and metal oxide film resistor. According to whether the resistance can be divided into variable resistor trimming, adjustable resistor, potentiometer.
