How Resistors Work - Unravel the Mysteries
of How Resistors Work!

Why Do Resistors Burst into Flames?
There are different types of resistors available in the market.
These resistors have distinct properties and materials that
determine their functionality. One type of resistor is the carbon
composite resistor.
Carbon composite resistors are made up of a mixture of
conducting material like carbon or graphite and an insulating
powder like clay. The mixture forms a solid core and metal
connectors are placed at each end. These resistors generate
heat, and if they are not able to dissipate sufficient heat, the
temperature increases to the point where the protective layer
catches fire and the resistor is destroyed.
Metal film resistors are also commonly used. They consist of a
ceramic core coated with a thin layer of metal. The size of a
metal film resistor determines its rating and the level of heat it
can dissipate.
The resistance value of metal film resistors is indicated by five
stripes on the resistor. The packaging usually tells us the
resistance, or we can confirm using a multimeter.
If you are wondering if a resistor should be placed before or after
an LED in a circuit, leave a comment below, and we will provide
the answer at the end of the video.
Wire wound resistors come in different designs and offer very
high power and current ratings. They are made of just a wire
wrapped around a ceramic core and covered with a thin layer of
insulation. The thickness, length, and material used dictate the
resistance of these resistors.
Potentiometers have a dial that lets us change the resistance.
There are general use versions used for volume control, and
