What best defines resistance? (2024)

What best defines resistance?

The statement that best defines the resistance of an electric circuit is: "It limits the amount of electrical energy that can pass through a circuit."Resistance is a property of an electric circuit that describes how much the circuit opposes the flow of electrical current.

What is the best way to describe 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). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Which of the following is the best definition of resistance?

the act or power of resisting, opposing, or withstanding. the opposition offered by one thing, force, etc., to another.

What determines resistance?

How much resistance a material has depends on several factors: the type of material, its width, its length, and its temperature. All materials have some resistance, but certain materials resist the flow of electric current more or less than other materials do.

What is the definition of resistance quizlet?

Resistance. The measure of how difficult it is for charges to flow through a material.

What are the 3 types of resistance?

There are three types of resistance, Logical/Rational, Psychological/Emotional, and Sociological. As a person who is facilitating Change, you should expect to experience each of these from employees.

What is an easy example of resistance?

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. This situation is certainly similar to an electron trying to make its way through a wire.

What is the simple of resistance?

An object that has simple resistance is called a resistor, even if its resistance is small. The unit for resistance is an ohm and is given the symbol Ω (upper case Greek omega). Rearrranging I=V/R gives R=V/I, and so the units of resistance are 1 ohm = 1 volt per ampere: 1Ω=1VA.

What are 3 synonyms for resistance?

What is the rule of resistance?

If the temperature and other physical variables stay constant, the resistance of a conductor is exactly proportional to its length. It means that R ∝ l , i.e., if the length rises, the resistance increases as well, and if the length reduces, the resistance lowers as well.

What is one of resistance?

Ohm (Ω) is the unit of resistance. One ohm is defined as that resistance of an object when a current of 1 Ampere flows through an object having a voltage(potential difference) of 1 Volt.

What are the two main types of resistance?

Static resistance is associated with circuits through which direct current is flowing, and it is the ratio between the voltage applied across the circuit and the current flowing through the circuit. Dynamic resistance is related to the circuits through which alternating current is flowing.

What affects resistance the most?

Factors Affecting Resistance include material, length, cross-sectional area, and temperature. The type of material determines its resistivity, while longer conductors cause more resistance.

What 3 factors does resistance depend on?

Length of wire: Resistance is directly proportional to the length of a wire. Area of a cross-section of wire: Resistance is inversely proportional to the area of cross-section the wire. The temperature of the wire: Resistance of a wire is directly proportional to the temperature of the wire.

What three things does resistance depend on?

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.

What is the definition of response to resistance?

Response to Resistance or Aggression (RRA) – An officer's response to an individual's. resistance to an officer's performance of duties, or aggression or threat of aggression. against an officer or another person. Y. Restraint – A mechanical or physical means for limiting an individual's freedom of movement.

Which of the following is true for resistance?

resistance is directly proportional to length of wire. therefore option (a) is right answer.

What is the definition of the resistance of a conductor answer?

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

What is the most common type of resistance?

Fixed Resistors

The fixed resistor type is the most common resistor. When people talk about a resistor, they most likely mean a fixed resistor. The picture to the right shows an axial carbon film resistor, the most common type on older printed circuit boards (PCBs) that used through-hold components.

What is resistance explained for kids?

It happens when two objects rub together creating a resistance of motion. It works against the motion and in the other direction. Like if you're trying to slide a piece of furniture along the floor in your house, it's going to be easier to slide on laminate or wooden floor than it is on the carpet.

What is an everyday example of resistance?

Further, resistance exists in the disguised form (low profile, undisclosed or “infrapolitics”) as everyday resistance (e.g. poaching, squatting, desertion, evasion, foot-dragging); (4) direct resistance by disguised resisters against material domination; (5) hidden transcripts of anger or disguised discourses of ...

What is resistance for kids?

Resistance - a force that opposes or slows down another force.

What is the common symbol of resistance?

The ohm (symbol: Ω, the uppercase Greek letter omega) is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Simon Ohm.

What is the 4th law of resistance?

The Fourth Law states that “the conducting material depends on its temperature”. According to this law when the temperature of a metallic conductor is increased, it's value also increases. From the first, second and third law, the resistance of a material can be given as R ∝ L/A. i.e R = ρL/A.

What is the base word of resistance?

Digging Through the Layers of Time: exposing the distant PIE roots. 'Resistance' as a noun has been around since the mid 14th c. It's meaning from Latin resistere is to make a stand, to oppose. In 1939 the term extended to include the concept of an organized, covert position.
