Which type of resistor is better to use? FIXED or VARIABLE? Why
do you say so?
Defend your answers below :D

Circuits with LEDs use fixed resistors to limit the current,
thus protecting the LED from damage.
A variable resistor, commonly called a potentiometer, allows you
to adjust the resistance.
Therefore, I would prefer on a fixed resistors, to limit the
current. It's a play safe strategy.

A fixed resistor cannot be changed as it is set at a specific
value, whereas a variable resistor can manage flows at and below
a specific level.
i choose variable resistor so thet if ever we need to change or
control the flow of current of we can control it

Same with De Guzman maam fixed resistor cannot be change while
variable resistor can be change.The differentiate of variable
and fixed are variable resistor you can manage the flow of
voltage while fixed to "restrict".
So I choose variable maam because variable can be change even
theres a damage same with my pcb maam variable resistor is also
called potentiometer you can manage the flow of voltage.

I AGREED WITH MR CHRISIAN DE GUZMAN ..ITS ABOUT THE
DISADVANATAGE AND ADVANTAGES OF THE RESISTOR

I prefer variable because we can change the value unlike fixed,
it has a specific value and it can't be change. And variable
seems more convenient and useful. :D :D :D

Variable Resistor so the value can be adjusted as per
requirement by adjustable component.

Ma'am i think it's better to use Variable or adjustable
resistors are often needed within electronic circuits to act as
a preset control within the circuit. The variable resistor, is
also widely referred to as a potentiometer as a result of its
configuration.
While it is often considered poor design practice to include
unnecessary adjustments in a circuit, the variations in circuit
values may mean that a preset, or variable resistor may be
required in order to set the circuit to function within its
required limits.The variable resistor comprises a fixed
resistive element along which a slider passes. The variable or
adjust able resistor forms a potential divider in which the
overall resistance between the two end points remains the same,
but the ratio of the two resistors in the legs changes.
Additionally, variable resistors are used for controls - a prime
example is the volume control on a radio, television of hi-fi
unit.

I WOULD PREFER USING THE FIXED RESISTOR BECAUSE IT CANNOT BE
CHANGED AND IT ALREADY GIVES US THE SPECIFIC VALUE THAT WE NEED.

for me it's better to use variable resistor,example of this is
the POTENTIOMETER , cuz we can change the value of resistance.
like when we need to adjust the volume the speaker of the TV,
change the output of our power supply and etc.
