## 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 the correct definition for resistance?

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

## What is resistance and its formula?

Resistance Formula The resistance formula is as follows: Resistance = voltage drop across a resistor/ current flowing through a resistor. R = frac{V}{I} R = resistance (Ohms, Ω) V = voltage difference which is between the two ends of a resistor (Volts, V)

## What is resistance BYJU’s?

Resistance is the measure of opposition applied by any object to the flow of electric current. Resistance is measured in ohms (Ω). Resistance Formula is used to compute the resistance across any given number of resistors in the circuit.

## What’s an example of resistance?

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 definition of deplored?

transitive verb. 1a: to feel or express grief for deplore the death of a friend. b: to regret strongly deplore my own actions. 2: to consider unfortunate or deserving of deprecation many critics deplore his methods.

## What is resistance and what is its unit?

Resistance is the property of a conductor to resist the flow of current through it. Its S.I. unit is ohm, represented by the Greek letter Ω (omega).

## What is resistance unit?

The unit of the electrical resistance, measured with direct current, is the ohm (abbreviated Ω), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm’s law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I.

## How do you use sentence 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.

## What is current formula?

The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).

## How do I 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 is the cause of 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 are the factors of resistance?

There are several factors that affect the resistance of a conductor;

- material, eg copper, has lower resistance than steel.
- length – longer wires have greater resistance.
- thickness – smaller diameter wires have greater resistance.
- temperature – heating a wire increases its resistance.

## What is the difference between resistance and resistivity?

Resistance is defined as the property of the conductor which opposes the flow of electric current. Resistivity is defined as the resistance offered by the material per unit length for unit cross-section. The SI unit of resistivity is Ohm.
