Question

what is meant by a resistor and what are the types of the resistor

Answer 1

meant -Resistor is like acurrent limiter. It limits the amount of current flowing through a device.Suppose you have to apply a certain current of 5 amperes to a device input and you have 10 amperes source so what wouldyou do ?solution : Add a resistor in series to limit the current.This resistance will create avoltage drop(reduces voltage in that area or drops potential) thus reducing the current passing through it.*.Current is defined as amount of charge flowing in a given time so you basicallylimit the flow of electrons (or you RESIST the flow of electrons).*.In the process of limiting the flow of current and reducing voltage, a resistor absorbselectrical energy, which is released in the form of heat.what can you do to reduce the current or limit the current ??What's going on inside a resistor?If you break one resistor , and scratch off the outer coating of insulating paint, you might see an insulating ceramic rod running through the middle with copper wire wrapped around the outside. A resistor like this is described as wire-wound. The number of copper turns controls the resistance very precisely: the more copper turns, and the thinner the copper, the higher the resistance. In smaller-value resistors, designed for lower-power circuits, the copper winding is replaced by a spiral pattern of carbon. Resistors likethis are much cheaper to make and are called carbon-film. Generally, wire-wound resistors are more precise and more stable at higher operating temperatures.

Answer 2

A resistor means a component which obstructs the flow of electro current and types of resistors are linear variable and fixed resistors
