It resist the flow of current according to the resistance value.
Resistors are one of the three basic electronic components. They restrict the flow of current in an electrical circuit. Fixed resistors have a fixed value of resistance, and are used in almost every electronic circuit for lots of different reasons.
In order to answer that, one would need to know what the circuit is designed to do (so that he would know how to tell when the circuit is "working"), and would also need to see the schematic diagram, in order to know exactly how the fixed resistor and the thermistor are configured in the circuit, and what other components are involved. Consider . . . If I came up to you on the street, or even for that matter in an Engineering lab, and I said to you "I've got a circuit with a coil and a resistor in it. Will it work if the impedance of the coil is greater than the resistance of the resistor ?", you would most certainly find yourself at a loss, just as I do when I read your question.
A resistor.
If the DC voltage of 120 volts is feeding series circuit consisting of 2-ohm, 6-ohm, and 8-ohm regular resistors, the variable resistor for line ammeter to indicate 1.5 amp, the variable resistor must be fixed before the amp.
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.

what does a resistor in an ampliflyer circuit
it is a switching device that need a current..so u will need a resistor to open the switch..
how connect a variable resistor to circuit

if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
In an electronic circuit power supply voltage is generally fixed. Resistors is a current limiter for correct devices polarization.
Any part of a circuit that has a voltage drop across it is a resistor.
A resistor.
its the colour of the fixed and the variable we define it by its power and name
No. A fixed resistor cannot be used as a dimmer in a lighting circuit. Depending on the dimming setting, you would need to dissipate substantial power across the resistor. What you need instead is some kind of pulse width modulated device, such as an SCR or TRIAC, or switching power supply, that does not dissipate a lot of power when it is turned on, because it operates in saturated mode, but the average power delivered to the load is what you want it to be.
It is used to vary the voltage/current flow in a circuit.
