Resistor
It is mainly used for making potential divider arrangements.
•
Resistor is the electronic component use to
reduce the flow of current.
•
Resistors are available at ¼, ½, 1, 2, 4 Watts
and we need to select the appropriate one we need depending upon the voltage
drop and current flowing through that.
•
In our usual circuits working under 5 to 25
volts we use ¼ W resistors and its size will be small.
•
The value of resistor is being calculated using
the color codes given in that.
•
Variable resistors are the resistors whose value
could be changed
•
They are of mainly two types: Preset type and
Potentiometer Type
•
They are being characterized by the maximum
resistance it could offer.
•
It is mainly used for making potential divider arrangements.
Testing With A Multimeter
•
Select the resistance range in the multimeter
•
Check the resistor with that and get the
resistence reading value from that.
•
Compare that value with the one given in the
color code. If both the vales remains same within the tolerance range, then it
is working fine.
