Hardware & V-modelVariable Resistors Linear -logarithmic

A linear potentiometer has a resistive element of constant cross-section, resulting in a device where the resistance between the contact (wiper) and one end terminal is proportional to the distance between themA logarithmic potentiometer has a resistive element that either 'tapers' in from one end to the other, or is made from a material whose resistivity varies from one end to the other. This results in a device where output voltage is a logarithmic function of the slider position.

Hardware & V-modelPower

Resistors are rated by the value of their resistance and the Electrical Power in Watts, (W) that they can safely dissipate based mainly upon their size. Every resistor has a maximum power rating which is determined

by its physical size as generally, the greater its surface area the more power it can dissipate safely into the ambient air or into a heatsink.
