Definition

It is a type of electrical device
that has the ability to resist the
flow of electric current. Made
with resistance wire or carbon
charcoal, etc.

Construction



Some of these fixed-value
resistors are made of carbon
coated with plastic or ceramic.
solid black or brown Some
resistors are made of metal
oxide compounds. This type of
resistor is generally There will
be a small error (Tolerance) or a
value of accuracy, reliability, as
told that the value that can be

hit is high.

Principle



Resistors act to reduce the flow
of current and at the same time
act to reduce the voltage level

within the common circuit. It
could be a fixed resistance. or
variable resistance such as those
found in thermistor, varistor,

trimmer, photoresistor and
potentiometer.

Appilcation

RESISTORS ARE USED IN THE
FOLLOWING WAYS:

In shunt with ampere metre
applications where balanced current
regulation, high sensitivity, and
precise measurement are required,
wire-wrapped resistors are used.
Photo resistors are used in flame
detectors, burglar alarms, and
photographic devices, among other
things.
Resistors are used to control
temperature and voltmeter readings.
Digital multimeters, amplifiers,
telecommunications, and oscillators
all employ resistors.
Modulators, demodulators, and
transmitters all use them.
