Resistors

Fixed Value Resistor (Wirewound)

For high power applications ------- are often used, the aluminium housing as shown in the picture is often used for power ratings from 10-250W.

Light Dependent Resistor (LDR)

Theresistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity.

What is a resistor?

a component of an electrical circuit that has resistance and is used to control the flow of electric current

Variable Resistor (Rheostat)

are very similar in construction to potentiometers, but are not used as a potential divider, but as a variable resistance. They use only 2 terminals instead of the 3 terminals potentiometers use

Fixed Value Resistor (IEC Symbol and IEEE Symbol)

have a defined ohmic resistance and are not adjustable. Fixed resistors are the most commonly used resistors and in general one of the most used electronic components.

Variable resistor

is a resistor of which the electric resistance value can be adjusted

Fixed Value Resistor (Carbon Film)

is the most common axial leaded resistor which is used for applications where a very good tolerance and temperature coefficient are not necessary

Variable Resistor (Potentiometers)

is the most common variable resistor. It functions as a potential divider and is used to generate a voltage signal depending on the position
