RESISTORS

Resistors opposes the flow of current, we use a various type of resistors , like

1.carbon composition
2.carbon film
3.metal film
4.wire wound
5.potentiometer
6.rehostat
7.trimmer etc.
there is a special type of photo sensor resisror called     LDR(light dependent resistor) , in upcoming projects we will use LDR
FIND THE VALUE OF RESISTANCE:-we can FIND THE VALUE OF RESISTANCE by a multimeter,or manually by colour code,
from where you can buy it and market price:- you can buy it from any electronics shop, i buy it from chandni market, kolkata,
    price: 100 piece with about RS 25
