What is meaning of resistant?
Being resistant means to be immune or impervious to something.
A vest that’s resistant to bullets is bullet-proof.
Anything resistant has a certain power — specifically, the power to resist or fight off — something else..
How many ohms is a short?
In theory a true short is completely zero ohms but in practice, all things have resistance, so a short is more typically a low resistance connection.
Does higher resistance mean more heat?
A higher resistance produces more heat. The time, t for which current flows. The longer the time the larger the amount of heat produced. … the higher the current the larger the amount of heat generated.
What is resistance and example?
Licensed from iStockPhoto. noun. 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.
Is high resistance Good or bad?
Resistor Symbols Low resistance, for example 1Ω or less implies that the circuit is a good conductor made from materials such as copper, aluminium or carbon while a high resistance, 1MΩ or more implies the circuit is a bad conductor made from insulating materials such as glass, porcelain or plastic.
What is a high resistance reading?
Higher numbers indicate a higher resistance rating, which means more energy will be required to integrate the component in a circuit. When you test a resistor, capacitor, or another electronic component, the ohmmeter will display a number indicating its resistance.

What does deplored mean?
verb (used with object), de·plored, de·plor·ing. to regret deeply or strongly; lament: to deplore the present state of morality. to disapprove of; censure. to feel or express deep grief for or in regard to: The class deplored the death of their teacher.
What are the 4 factors that affect resistance?
There are 4 different factors which affect resistance:The type of material of which the resistor is made.The length of the resistor.The thickness of the resistor.The temperature of the conductor.
What is resistance easy definition?
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). … Conductors: Materials that offer very little resistance where electrons can move easily.
What is resistance and unit?
Siemens per meterElectrical conductivityOhm meterElectrical resistivityElectrical resistance and conductance/SI units
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 formula?
The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm’s law, I = V/R, can be used to predict the behavior of the material.
How do I measure resistance?
Resistance is measured in ohms; 1 ohm is equal to 1 volt of electrical difference per 1 ampere of current (1 volt/1 amp). You’ll find your volt of electrical difference by taking several readings using your equipment. Resistance can be measured with an analog or digital multimeter or ohmmeter.
What is the difference between resistance and resistant?
As nouns the difference between resistance and resistant is that resistance is the act of resisting, or the capacity to resist while resistant is a person who resists; especially a member of a resistance movement.
Why is resistance directly proportional to length?
Directly proportional ; as the length of the wire increases , its resistance increases. Why? Simply speaking,the longer the distance the electron has to travel ,the more collisions it will face with the atoms ; which means higher resistance.
How do I calculate resistance?
Ohms Law and PowerTo find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
What happens if resistance is too high?
A high resistance in the circuit means a very low current flowing in it when the voltage of the source is constant. … Low resistance in the circuit means a higher current is flowing in the circuit. It depletes the battery at a faster rate which means the battery can not last for a long time.
What is the relation between length and resistance?
Resistance depends on an object’s size, shape, and material. In Figure 3 below, the cylinder’s resistance is directly proportional to its length l. The longer the cylinder, the higher the resistance. Additionally, the resistance is inversely proportional to the cross sectional area A.
