One use is as a current limiter. For example if a certain device (like a capacitor) is capable of being in conditions similar to a short circuit, the amount of current "drawn" by the capacitor could be damaging to it or other components. Placing a resistor in series with the capacitor means that you can select the proper resistor so that at maximum capable volt, you know the maximum current that will flow through that value resistor according to Ohms Law.
Another use is to design to have a desired voltage present in certain parts of the circuit.

Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors?
False.
Does more current flow through a parallel circuit than a series circuit?
Two resistors in parallel are equivalent to a single component with a lower resistance than either of the pair. Two resistors in series are equivalent to a single component with a resistance equal to the sum of the pair, therefore a higher resistance. For a given potential difference, more current in total will flow through two resistors in parallel than through the same resistors in series.
Did the the total voltage across the resistors does not depend on the resistor value?
It depends on where and how the resistor is placed in a circuit. A string of series resistors will split the voltage across all them depending on their values. All of the resistors in parallel will have the same voltage across all of them no matter what their resistance is.
What is the equivalent resistance through the entire circuit?
The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.
Why do you use a variable resistor?
The characteristics of some circuit components cannot be predicted with complete accuracy. Variable resistors are provided in circuits involving these components sometimes to make up for these unavoidable variations.Variable resistors are often used to make it possible for users set suitable volumes in headphones and speakers.Variable resistors may be used to set time constants in circuits that also include capacitive or inductive elements.
Why do people use resistors in an electric circuit?
we use resistors in an electric circuit to describe how a wire works and to control the flow of electricity
What resistors do in oscillator circuit?
The same thing they do in every circuit, resist the flow of electricity. That being said there are Many types of ossilators, and they can use resistors for many purposes.
Why do you use resistors and capacitors in any electronic circuit?
because their effects are desired to make the circuit work
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Why resistors are connecting?
resistors are used to resist the flow of current in a circuit.......
What type of circuit is it when capacitors are combined with resistors?
RC Circuit
What type of circuit has all its resistors in the same path?
A series circuit
Can you use a battery to make electricity?
make a electric circuit,by using resistors,cll then electricity is produced.
Why do you use resistor in electronics?
we use resistors to offer opposition to the flow of electric current. Resistors absorbs power from the circuit and convert it into heat that is why they are normally rated for the maximum amount of power that they can salfely handle
What is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
What controls the flow of electricity in a circuit?
RESISTORS ......no
What kind of circuit do you have when all resistors are in a single pathway?
its called a complete circuit
