How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
Are wire wound resistors used in parallel circuits?
Can be. Wire wound resistors might take more power, or offer better precision, or custom resistance values. Wherever, whenever those features are desirable, whether its a series or parallell circuit, a wire wound resistor might be used.
What are specifications of resistor?
The resistance, the precision of that value, the thermal or electrical environment, the style of indicating these values. There are wire-wound resistors, cracked carbon resistors, carbon resistors and so on.
What are the applications of precision rectifiers?
Precision rectifiers are used in the design of instrumentation systems.
What are the types of carbon film resistors?
Carbon film resistors come in several types, primarily differentiated by their construction and performance characteristics. The most common types include standard carbon film resistors, which offer good stability and low noise, and high-precision carbon film resistors, designed for applications requiring tighter tolerances. Other variations include low-temperature coefficient (LTC) carbon film resistors, which minimize changes in resistance with temperature, and power carbon film resistors, built to handle higher power ratings. Each type is suited for different applications based on factors like accuracy, stability, and power handling capabilities.
What is carbon composition?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
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.

What are those materials of resistors?
most of the resistors commonly used are carbon resistors
What is precision resistor?
A precision resistor is a resistor that has an actual value that is very close (or precise) to its nominal (or stated value). Therefore, precision resistors have a very degree of accuracy of being very close to their nominal values.
What are resistors and why are they used?
Resistors are like funnels, they restrict the flow of current.
Why resistors are connecting?
resistors are used to resist the flow of current in a circuit.......

What are advantages of a series combination of resistors?
parallel combination of resistors are used in house circuits
Why resistors have tolerances?
Some design engineers that make electronic circuits specify tolerances in the resistors because a resistor that is too out of spec would not operate properly. A resistor with a brown band I believe is within 20%, a black is 10%, and gold is 5%. So if a resistor is rated at 3000 ohms, depending upon the band, it can vary a certain percentage. Resistors with the gold band I believe are called "precision resistors". The more "precision" the resistor is, the more it costs. To keep costs low, tolerances are sometimes included to alert the assembler that a precision resistor may not be necessary. For instance if a value of 3000 ohms can be within 20% then a cheap resistor may be used and is not critical in the circuit. The tolerances are introduced in manufacturing of resistors because practically, we can achieve 100% correct resistance. So, a tolerance range is indicated to make aware the users to select the proper resistor according to their application.
