A preset resistor is used in some circuits to change the resistance. The preset resistor enables the circuit to be more or less sensitive thereby altering the resistance.

Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
What does a series circuit not have?
a resistor
Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
What is RC in electrical?
R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.
What is a preset resister?
A preset resistor also known as a poteintometer is a type of resistor whos resistance is selected by the user. A preset maybe of any range i.e. from 1k to 100k or from 1M to 100M. a preset is used in many circuits where varyin resistance is required

What parts of a circuit acts as a resistor?
Any part of a circuit that has a voltage drop across it is a resistor.
A can be used to reduce the current in a circuit?
A resistor.

What is a single resistor the represents a complex circuit?
Equivalent Resistor
Function of resistor capacitor and transistor on integrated circuit?
resistor
What does a series circuit not have?
a resistor
What is a function of a resistor in a fire alarm circuit?
A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.
