What is resistor short answer?

A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.

What is resistor example?

A resistor is a device that shows resistance of a passage of electric current. For example, ohmic resistors. Resistors can be of a fixed value, for example: 100 Ohms, (100Ω) or variable as in 0 to 100Ω.

What is resistor and its unit?

Resistor is an electrical component that reduces the electric current. The resistor’s ability to reduce the current is called resistance and is measured in units of ohms (symbol: Ω). If we make an analogy to water flow through pipes, the resistor is a thin pipe that reduces the water flow.

What are the 4 types of resistors?

Types of Resistors

  • Fixed Value Resistors. These are the predominant type of resistor configuration, and as the name suggests, they have a fixed resistance value.
  • Variable Resistors.
  • Resistor Networks.
  • Carbon Film Resistors.
  • Metal Film Resistors.
  • Wirewound Resistors.
  • Metal Oxide Resistors.
  • Metal Strip Resistors.

What is a resistor Class 6?

Resistor is defined as. A passive electrical component with two terminals that are used for either limiting or regulating the flow of electric current in electrical circuits. The main purpose of resistor is to reduce the current flow and to lower the voltage in any particular portion of the circuit.

What happens if I use a higher ohm resistor?

The cases where using a higher value resistor will damage a circuit exist, but are a bit less usual than the cases where it may simply produce a weaker result than desired, or a different frequency response than desired.

Why do you need a resistor in a circuit?

In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

What is the main function of resistor?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

How do you classify a resistor?

Classification of resistors Categorized by function, there are three types of resistors; fixed resistors, used in a electric circuit; trimmer potentiometer to adjust a circuit; variable resistor, used as a radio volume by changing the resistance.

What is the most common type of resistor?

Carbon Resistors
Carbon Resistors are the most common type of Composition Resistors. Carbon resistors are a cheap general purpose resistor used in electrical and electronic circuits.

Does a resistor reduce voltage?

If a component in your circuit requires less voltage than the rest of your circuit, a resistor will create a voltage drop to ensure the component does not receive too much voltage. The resistor will create a voltage drop by slowing down, or resisting, the electrons as they try to flow through the resistor.

What does resister mean?

Definition of resister. : one that resists especially : one who actively opposes the policies of a government.

What is different between diode and resister?

As nouns the difference between diode and resistor is that diode is an electronic device that allows current to flow in one direction only; a valve while resistor is one who resists, especially a person who fights against an occupying army. Other Comparisons: What’s the difference?

What is a resister person?

resistor (plural resistors) One who resists, especially a person who fights against an occupying army. An electric component that transmits current in direct proportion to the voltage across it.

What is the difference between a resistor and an insulator?

An insulator is a material which doesn’t conduct electricity, ie, it doesn’t allow the flow of electrons to flow through it. A resistor, however, is a device which simply provides resistance to the flow of electrons.
