Perhaps you will appreciate all such doubt by a casual study of principles of electricity and electronics fundamentals. One such book is listed here
it is ON line free https://www.mikroe.com/en/books/keu/00.htm
After a casual study you may return back for further clarification if at all.
All the best
well good question i guess for someone new ..... i wana explain it from a common and daily example.
when u r in car driving it its engine has a rated speed . suppose all the time ur engine is producing a speed (say it s) that is 100km/h. now there is a narrow and difficult road which required a speed of 20km/h . what u will do there ... u will apply breaks.. and decrease ur speed from 100km/h to 20km/h and u r wasting the speed of 80km/h for nothing. now breaks are analogous r alike resister . and 80km/h speed is wasted this is called resistor losses.
capacitor is like ur water tank which may b on the roof of ur house and which get supply from a huge tank of city r from other source. the tank on ur roof is used by u for the supply of water when it is needed . r we can say capacitor is analogous to the water tank on ur house roof means its a energy storage element . this is the simplest explanation that i can give to u .
also u can go on other webs that can b helpfull to understand these elements
as what have been said, in general resistor is used in electronic circuits to resist the flow of current while capacitors are used in storing energy and it is sometime used in preventing noise in the circuit. these two devices are classified to be a passive device, since they are not capable of amplifying signal. as you go on reading some books regarding electronics you will find out the different types of active devices which amplifies signal.
After you've researched the basic information about resistors and capacitors it may well be worthwhile to research filters. Here's a short introduction..
R-C low pass filter
C-R high pass filter
Used in combination..
either..
Band Pass Filter
OR
Band Reject Filter
You haven't even touched the tip of the iceberg yet =).. Good Luck.
There are a lot of states where resistors and capacitors are used in the electrical and electronic circuits. You should read a book about electrical circuits and one microelectronic book to learn about this issue.
to make things easier let us consider a more easier example: water
water flows through a pipe the tap is used to resist the flow of water right?
a tank is used to fill the water in
now consider electricity. Current flows in the wire. Depending on the value of resitor used you can resist the flow of current.
If there exist a capacitor on the way, the capacitor is like the tank of water.
if current is passed through it, (water will be filled) we say the capacitor is beeing charged.
in the water example we will have amount of water in electricity we will get voltage.
This is the simplest way.

Hi All,
Resistors are used to limit currents or divide voltages. Capacitors are used to store charges hence stabilize voltages. Capacitors are also used to filter unwanted AC signals.
