You want a filter to remove energy at only certain frequencies, and not to
have any affect on all the others. Resistors just dissipate energy, regardless
of what its frequency may be.

What are advantages of a series combination of resistors?
parallel combination of resistors are used in house circuits
Can resistors function the same in AC circuits as in DC circuits?
Yes, they both can add a load to a circuit.
What protects circuits from dangerously large currents?
resistors circuit breakers fuses
What are some simple electronic devices that are used in electrical engineering?
Resistors, capacitors, inductors, transformers, diodes, transistors, integrated circuits, power sources are the basic building blocks.
What kinds of circuits need precise resistors?
Timing circuits, and any circuit that depends on the resistor value being fairly precise, such as voltage dividers and comparators. Old story....engineers knew that you couldn't pick through a bunch of loose precision resistors to find close tolerance resistors....The manufacurer already took the close precision resistors and sold them separately. This is not so true these days. Even low tolerance resistors might be high precision. Usually the manufacturer will fill the loose precision needs with parts better than required.
Why RC circuit is preferred over RL circuit in waveshaping?
There is no true advantage of RC circuits over RL circuits, as they perform different functions. RC circuits contain resistors and capacitors, while RL circuits contain resistors and inductors.
What are advantages of a series combination of resistors?
parallel combination of resistors are used in house circuits
What type of resistor is used for automotive circuits?
Which type of resistor is commonly used in automotive circuits?
Why do you need resistors?
Resistors are used for a variety of purposes: to allow voltage levels to be reduced when in series circuits, to bleed off capacitors, to assert the output level of tri-state or open collector microchips and to protect circuits from damage.
What are RC circuits used for?
RC circuits can be used to filter a signal by blocking certain frequencies and passing others.
What products use resistors?
allmost every electronic devices uses resistors..(it is needed in all circuits)
How do you wire Resistors required for led combination circuits?
in series
Can resistors function the same in AC circuits as in DC circuits?
Yes, they both can add a load to a circuit.
What type of capacitor is often used in power-supply circuits to filter the rectified AC?
The electrolytic capacitor is most often used in power supply circuits to filter the rectified AC.
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.
What are the differences between analog and digital filters?
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
What is the relationship between you and R in networks of parallel resistors in electric circuits?
