What is an easy definition for resistance?

What is an easy definition for resistance?

1 : an act or instance of opposing. 2 : the ability to withstand the force or effect of resistance to disease. 3 : an opposing or slowing force The car’s sleek design reduces wind resistance. 4 : the opposition offered by a substance to the passage through it of an electric current.

What is resistance electrical engineering?

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).

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?

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.

What is a resistance example?

Resistance is defined as a refusal to give in or to something that slows down or prevents something. An example of resistance is a child fighting against her kidnapper. An example of resistance is wind against the wings of a plane.

What is resistance a level physics?

Resistance is defined as the opposition to current. For a given potential difference: The higher the resistance the lower the current.

What is a resistance science?

resistance. [ rĭ-zĭs′təns ] A force, such as friction, that operates opposite the direction of motion of a body and tends to prevent or slow down the body’s motion. A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms.

What is resistance class 10 Ncert?

Resistance is a property of conductor due to which it resists or opposes the flow of electric current through it. The way a surface offers resistance to movement by offering friction, conductors oppose the flow of current.

What is resistance class 7th?

1. Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. When an electric current passes through a high resistance wire, the electric energy gets converted into heat energy. This heat energy heats up the resistance wire.

How do you explain resistance to a child?

Resistance – Resistance measures how well a material or object conducts electricity. Low resistance means the object conducts electricity well, high resistance means the object does not conduct electricity well.
