Resistor is an eletrical and electronical part whose function is to decrease the value of the voltage in a circuit, consequently reducing the value of the current, which is measured in Amperes.

What is A Resistor In A conductor?

Resistors and conductors are actually two sides of the same story. They both conduct electricity and they both resist conducting electricity. The difference is how well they conduct electricity. Copper, Silver and Aluminum are examples of brilliant conductors. They resist very little. Coal-fibers and various metal oxides are examples of poor conductors. They resist much more and falls into the category of being a resistor. The comparison can easily be made with a water pipe-line. A huge dimension can carry a lot of water (This is electrical current). It can also contain high pressure (In this analogy, that would be Voltage) A very small dimension can not carry much water at all (The current is limited. This is what physically happens in a resistor.) The water pressure is the same, then the big pipe might fill a bathtub in 30 seconds where as the small pipe would maybe need 10 minutes or more. It works "exactly" the same way with electric components as conductors and resistors. Some people claim that a conductor is the opposite of a resistor. This is a wrongful interpretation although it seems to make sense... They are both conductors of voltage (water pressure as an analogy). A resistor only limits the current, Amount of water in previous analogy, somewhat, this depending on the specifications of the resistor. A conductor is a good leader of the electricity and a resistor is damping the electricity.


What is the function of a cement resistor?

A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).

Voltmeter is connected in parallel with resistor?

A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.


What is series dropping resistor?

A series dropping resistor is a resistor that limits the amount of current flow in a circuit.

Why does a resistor get hot when electricity passes through it?

A resistor gets hot when electricity passes through it because the resistance in the resistor causes some of the electrical energy to be converted into heat energy. This heat energy is dissipated as the resistor resists the flow of electricity, leading to an increase in temperature.


How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?

A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.


In electricity what is the function of a resistor?

How does thevariable resistor control electricity?

A: it does not control electricity but Rather varies the potential subjected to.


What would could transform electricity to heat?

A resistor.


What is the difference between resistor and insulator?

A resistor is a component that limits the flow of electric current in a circuit, while an insulator is a material that restricts the flow of electricity. Resistors are used to control the amount of current in a circuit, whereas insulators are used to prevent the flow of electricity altogether.


What is a material which allows electricity to flow through it but with but with resistance?

What is a device that resists the flow of electricity in a circuit?

A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.


What is the name of the component that turns and controls or limits the flow of electricity?

A device that controls or limits the flow of electricity is called a resistor.
