ELECTRONIC COMPONENTS

2. Resistors are non-permanent (variable)
            Is the resistance value resistor or resistance can be changed.
Type, among others: the shear resistance, trimpot and potentiometers. Trimpot is widely used and potensimeter.

A. Potentiometer
Resistor resistance value can be changed by rotating shaft
which has been available. Potentiometer is basically the same functionally trimpot.

Trimpot
              Resistor resistance value can be changed by rotating
axis by using a screwdriver. To know the value of the resistance of a trimpot can be seen from the figures listed on the agency trimpot
them.
