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.
What else can I help you with?
What is the total resistance of twelve 5.6 ohms resistors in a row?
If they are in series, you need to add the resistance values.
How do you use thevenin's theorem to calculate current in resistors?
If this is an independent current source, it has to be disconnected.Independent voltage sources are replaced by a short-circuit.More about this at (see Related links):MasteringElectronicsDesign.com: How to Apply Thevenin's Theorem - Part 1, Solving Circuits with Independent SourcesandMasteringElectronicsDesign.com: How to Apply Thevenin's Theorem - Part 2.

How do circuits work?
Circuits need 3 things to work. They need a load, (what the power goes on) power source, (the battery) and connectors (the wire inbetween). Circuits use electrons to flow from the negative side of the battery and around the circuit back to the battery. This repeats until the circuit breaks.
Why do you need 330 ohm resistor for LED?
Generally 330ohm resistors are used to power a typical 3 volt LED if the source voltage is 5v
What are the specific practices and procedures that i need to observe when assembling and testing electronic circuits?

Why do resistors need to be precise?
A: Resistors are never precise they normally come with 5% tolerance. However if precise tolerance is needed one can purchase a precise resistor down to 0,01% or even lower % but these resistors are special and made special for each application
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.
How do you install tail light on a Mazda bt-50?
Due to the complex nature of the system, Load Resistors will need to be fitted in both the indicator circuits and stop light circuits. Possibility of also requireing them in the park light circuits but not confirmed.

How will you get 6.75 ohm resistance in combination of resistors bacause i have no any value resistor is available?
6.8 ohms is a standard value, and 6.8 is within 0.74% of 6.75. If you need a precise value, use a potentiometer or start playing with resistors, because resistors have tolerance and you will not be able to build an exact 6.75 by just looking at values - you need to measure combinations.
What will happen if you connect identical integrated circuits in series?
Connecting integrated circuits is not the same as the much simpler cases of resistors, capacitors, inductors, motors, light bulbs, etc. Integrated circuits have designated functions, and they operate in concert with the surrounding circuit design. As such, the idea of "connecting identical integrated circuits in series" has no meaning in the general case. You would need to state what kind of integrated circuit is involved.
Do you need to put a shunt resistor to connect the ac voltmetr?
Shunt resistors are used with ammeters; voltmeters require series resistors.
Do the resistors lie wwithin the tolerance limits?
To determine if the resistors lie within the tolerance limits, you need to compare the measured resistance values of the resistors with the specified range provided by the tolerance. If the measured resistance values fall within this specified range, then the resistors are within tolerance limits.
Where is the resistor located?
There are many resistors, need to know which one and which vehicle you have.
Why do you need circuits?
i dont know why is it
How are parallel resistors connected?
If you need a resistor of a certain value, and you have no resistors with small enough values,you can create the one you need by connecting several of those you have in parallel.The effective net resistance of resistors in parallel is always less than the smallest individual.And the more resistors you add in parallel, the smaller the net effective resistance becomes.
How to design a phase shifter circuit using operational amplifier to have a desired phase shift?
There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
