Resistance simple definition

Resistance means "refusal to comply with or accept something." An individual person can put up resistance against something she disagrees with or doesn't want to participate in. On a larger scale, groups of people and even whole countries can display resistance, like when the British put up resistance against Napoleon.

What is resistance and example?

Resistance refers to the amount that an object impedes or resists in an electric current. Electric current refers to the flow of electrons. An easier way to explain resistance is to consider an example of a person in a crowded market struggling to go from one shop to another.

What is a resistance for kids?

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.

What is a sentence for resistance?

Resistance sentence example. Any resistance she might have mustered melted at his words. Whatever resistance she had evaporated in the intensity of his desire for her. He lay staring at the ceiling for a time, attempting to push away the torment; it had gripped him so completely that resistance was futile.

Why resistance is used in circuit?

Resistor is used to resistance the flow of current. When resistor is placed in a circuit, the current flow decreases when current passes through the resistor. The part of current energy dissipate in the form of heat in resistor, thus decrease the total current.

What is a resistance class 8?

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 causes 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 resistance and its unit?

The resistance of a conductor is defined as the ratio of the potential difference across its end to the current flowing through it. Its SI unit is ohm (Ω).

What is resistance in friction?

Friction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction.

What is a resistor Class 3?

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 is a current for kids?

Current is the rate of flow of electrons. It's produced by moving electrons.

What is the synonym of resistance?

antagonism. nouncausing problem; opposition. animosity. animus. antipathy.

What is the synonym of resistant?

synonyms for resistant

contrary.
defiant.
disobedient.
opposing.
rebellious.
unyielding.

What does no resistance mean?

Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate a complete circuit, or one that has no short.

How do you measure resistance?

Resistance can be calculated by measuring the current and voltage using Ohm's Law. As a result, a circuit's resistance value can be determined if the current and voltage measured values are known. Analog multimeters and digital multimeters employ the measurement principle of Ohm's Law to measure resistance.

What will happen if no resistance?

If there really were no resistance in the circuit, the electrons would go around the circuit, and arrive back at the beginning of the circuit with as much energy as the potential difference (the voltage). That final energy is usually what is dissipated as heat or other types of energy by the circuit.

What is resistance in electric current?

Parameters	Resistance	Resistivity
Definition	When the flow of electrons is opposed in a material is known as resistance	When resistance is offered

Symbol	R	ρ

What is resistance BYJU's?

Resistance is the measure of opposition applied by any object to the flow of electric current. A resistor is an electronic constituent that is used in the circuit with the purpose of offering that specific amount of resistance. The resistance of any object is computed making use of the formula: R = V I.

What is resistance class 10 short answer?

Resistance is defined as the property of the conductor which opposes the flow of electric current. It is also defined as the ratio of the voltage applied to the electric current flowing through it.

What is resistivity Class 9?

A material's electrical resistivity is a measure of how strongly it opposes the flow of current. The ohm meter (m) is the SI unit of electrical resistivity. The Greek letter rho is commonly used to represent it. Conductors are materials that easily conduct current and have a low resistivity.
