Consequently, the construction (size, shape, and material type) of a resistor determines its resistance value. Four bands are placed on most resistors. When four bands are present: • The first band ...

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls.

A new surface-mount thick film power resistor offers robust 35 W power dissipation, durability across 100,000 pulses, and a ...
