How Does a Resistor Work in an Electrical Circuit

A resistor works by restricting the flow of current, it can do this in one of three ways: firstly, by using a less conductive material, secondly by making the conductive material thinner and finally by making the conductive material longer.

How does a resistor affect an electrical circuit?

Resistor reduces the flow rate of electrons . That results in potential difference across it. Even a conductor has certain resistance across its given length. Flow of electrons takes place under the effect of electric field.

What happens when current passes through a resistor?

When current is passed through a resistor some electrons are blocked and cannot move over and hence energy is released in the form of heat and hence current is decreased. The voltage which the current has will be reduced after the resistor.
