A resistor limits the amount of electrical current that passes through the circuit.
Think of kinking a garden hose. The kink "resists" the flow of water.
Similarly, a resistor "resists" the current flow and thus lowers the voltage to the following parts of the circuit which that current has to flow through.
Another answer
Simple...To resist or control the current flow.
If a pure conductor (ie, wire) instead of a resistor is used, the path is said to be short circuited and, in theory - but not usually in practice - an infinite current would flow through it if the source was really able to deliver such a current.
But, if there is some resistance in its path, the current taken from the source will always be limited to the potential difference produced by the source (measured in volts) divided by the resistance of the path (measured in ohms).
I = E/R (Where I is current, E is volts and R is resistance)
Another use of a resistor is whenever you need to produce a voltage drop in a circuit. This drop can can then be utilized for some other purpose, noting the voltage will differ depending on the load. If the load varies in resistance, so will the voltage drop.
When no resistors are met by the current, the voltage which is actually the amount of work done in moving the charge will tend to zero. This means that the current flows without any resistance and is said to be a dead short to the source.
A Resistor Is Used To Limit The Current In A Circuit
Further AnswerA resistor is sometimes used to modify the natural resistance of a circuit -e.g. by adding a resistor in series, you can increase the natural resistance; by adding a resistor in parallel, you can decrease the natural resistance. Two or more resistors can be used to create a voltage divider -a method of obtaining a voltage lower than the supply voltage in a d.c. circuit.
Use of resistor is to produce a particular amount of resistance to the flow of current
Resistors are used for many things in an electronic circuit, including creating a voltage drop at some point; attenuating noise on a signal before it reaches the output stage; in combination with transistor devices, split a signal into 2 opposite phases; present a minimum load to a device to keep it working at its optimum point; to create an appropriate bias level for transistor device inputs; to control a timing circuit in conjunction with a capacitor; to create a tuned circuit in conjunction with an inductor, and/or a capacitor . . . . and the list goes on . . .
It controls the amount of current that flows. A dead short (wires without resistance) would cause too much current to flow and overheat the wires.
The job of the resistor is to control the amount of electricity that flows through the circuit.
That's to ensure that not too much current passes through the diode, which would burn it.
To limit the current
Same as any other kind of resistor, they're used to control voltages and currents in electric circuits.
It depends on what sort of circuit the resistor(s) is in. The resistor(s) can lower either EMT (Voltage) or Current (Amperage) Sometime resistors are used to create an EMT differential whenever current is flowing.

what does a resistor in an ampliflyer circuit
Typically used in logic circuits is the pull-up resistor Less common is the pull-down resistor It's purpose is to force a zero (low) value when no other component is driving the input (no load) By providing a current limited path to negative power source through the resistor, while allowing the voltage to swing high if a load is present.
A resistor.
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
Which type of resistor is commonly used in automotive circuits?
the material we used is resistor because it did`t stop flowing.

I want you to tell me the answer
It does not have a ballast resistor, those were used for ignition systems 30+ years ago. It does have a blower motor resistor that is located behind the glove box.It does not have a ballast resistor, those were used for ignition systems 30+ years ago.

The resistors are mainly used to reduce the current
It is a resistor or a group of resisters used to control the flow or current in a circuit. Like the resistor block in a car controls the speed of the a/c blower.
