What is meant by electrical resistance class 10?

Resistance is a property of conductor due to which it resists the flow of electric current through it. Component that is used to resist the flow of electric current in a circuit is called resistor. In practical applications, resistors are used to increase or decrease the electric current.

What is meant by electrical resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). … All materials resist current flow to some degree.

What is electrical resistance simple words?

The electrical resistance of an electrical conductor is a measure of the difficulty of passing an electric current through a substance. … With more resistance in a circuit, less electricity will flow through the circuit. The inverse of resistance is conductance, a measure not much used.

What is meant by resistance of a conductor Class 10?

Conductor resistance is a property of a conductor at a specific temperature, and it is defined as the amount of opposition there is to the flow of electric current through a conducting medium.

What is meant by resistor Class 10?

Answer: a device having resistance to the passage of an electric current.

What is electric resistance and its unit?

Electric resistance has the dimension length squared mass per time cubed electric current squared. The SI derived unit of electric resistance is the ohm, which is defined as a volt per ampere.

What is electrical resistance class 12?

The property of a conductor by virtue of which it opposes the flow of electric current through it is called resistance. It is given by the ratio of voltage applied to the electric current which flows through it. R = V/I.

What is the best definition of electrical resistance?

Resistance is a property that resists the flow of electrons in a conductor. It controls the magnitude of the current. The SI unit of resistance is Ohm (Ω).

What is resistance class 9?

Resistance is defined as an opposition to current flow. An electrical circuit must have resistance in it in order to change electrical energy to light, heat or movement. … Resistance is an inherent opposition to the flow of electrons present in conductors.

What causes electrical resistance?

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.

What is the meant by electric resistance of a conductor?

Resistance is defined as the property of a conductor to resist the flow of charges through it. The resistance of conductor is numerically given as the ratio of potential difference across its length to the current flowing through it.

What is meant by electrical resistance of a conductor state how resistance of a conductor is affected?

Solution. Electric resistance of a conductor is the obstruction offered by the conductor to the flow of the current through it. Electric resistance depends on lenght,area,resistivity and temperature.It does not depend on current.

What is meant by resistance of a conductor name and define its?

Hint: Resistance of a conductor simply defined as when flow of current is opposed or resisted in a material it is known as resistance and effect of length and the radius on conductor can be given by R=ρlA where l is the length of the conductor and A is the area o0f the conductor. Formula used: R=VI.
