What is difference between resistor and resistance?
What is difference between resistor and resistance?
Resistance is designated with R and its unit is the ohm (Ω). A resistor is a device designed to produce resistance. Resistors can be used to limit current, divide voltage, or generate heat.
What is the main difference between resistance and resistivity?
Furthermore, an important difference between resistance and resistivity has to do with the flow of free electrons. Also, resistance is an aspect that opposes the flowing of free electrons. In contrast, resistivity is any material’s property that tells the resistance of the material with a particular dimension.
What is the difference between resistance and reactance?
Mathematically, resistance is simply voltage divided by current. Reactance is a property that opposes a change in current and is found in both inductors and capacitors. Because it only affects changing current, reactance is specific to AC power and depends on the frequency of the current.
What is the difference between registers and resistance?
Both are different. Registers are digital sequentail devices, and resistor is a passive electronic component. Resistors are used to reduce the current flow through an electronic circuit.
What is the difference between resistor and resistance class 10th?
Answer: Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.
What is resistor in simple words?
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.
What is the difference between resistance and resistivity Vedantu?
We define the resistance of a conductor as the obstruction posed by the conductor to the flow of electric current through it….Difference Between Resistance and Resistivity.
| Resistance | Resistivity |
|---|---|
| Depends upon the length, cross-sectional area and temperature of the material inside the conductor. | Depends upon the nature and temperature of the material. |
What is relation between resistance and resistivity?
Relation between Resistivity and Resistance is: R=ρlA, where ρ is the resistivity, l is the length of the conductor and A is the cross sectional area. We know that the resistivity of a material depends on the temperature.
What is difference between resistance and impedance?
It could be said that electrical resistance is the opposition to steady electric current. An ideal resistance does change with frequency when connected with DC. Impedance is the measure of the nature of opposition of the AC electricity which is created due to inductance and capacitance.
What is difference between resistance and inductor?
The main difference between ideal resistors and ideal inductors is therefore that resistors dissipate electrical power as heat, while inductors turn electrical power into a magnetic field. Ideal resistors have zero reactance and as a result zero inductance.
