What is the real life application of resistors with both parallel and series circuits?

Question

plss i need by today i beg you plss reply!!!!!o:-)

Answer 1

Real life circuits are much more complicated than simple strings of series or parallel resistors. But knowing how those work gives you a start at understanding the more complicated circuits.

Do a search of google for schematics and look at a few. You will see lots of resistors in various combinations, as well as other components.

Answer 2

Can you give us some more detail?  I'm not exactly sure I understand your question.

Resistors in parallel and in series are in just about everything you touch these days...

Edit:

Resistors are all over the place in both discrete and integrated circuits.  Additionally, knowing how to transform and simplify linear circuits (i.e. resistive circuits) is very useful in understanding much more complex circuits.  The primary pencil-and-paper method of solving circuits with transistors, for example is to "linearize" the transistor and represent it as a resistive circuit.  You then apply these elementary resistive circuit principles to these much more complex circuits.

Answer 3

Series and parallel resistors are mostly seen in analog circuit, mostly OP-AMP. These circuit uses parallel and series resistors to be used as adders or dividers of the incoming signals. They can also differentiate one signal from all other types of signals. Analog circuits is a real life application for parallel and series resistors configuration.

Answer 4

Your question seems based on an ignorance of electronic equipment. Short of using batteries to control the active devices, for every function of the device, resistors are crucial to the operation of literally everything around you that is electronic. Use your imagination, as well as get some schematics of various things such as TVs, radios, audio equipment, and computers. Nothing that is a practical device that is electronic can work without resistors. To give a detail, the basic transistor amplifier would be impossible without resistors in series, such as for setting the Base current value, or in parallel relative to the transistor for Collector circuit operation, and Emitter/Base biasing.

Answer 5

Resistors can take many forms. Perhaps the simplest one in everyday use is the incandescent light bulb. This is simply a resistor wire that is designed to get hot, so is the glowing element of an electric fire, or electric oven or hob.

In lighting applications, the light bulbs in various rooms operate in parallel.

A simple application that uses bulbs, IE resistors, in series is the lights on a Christmas tree, where if one bulb fails, all the bulbs on the tree go out.
