What else can I help you with?
When you pull out the plug connected to an electrical appliance you often observe a spark to which property of the appliance is this related?
I think it is due to the resistance to the electrical appliance, the resistance offered by the electrical appliance works as a load in the circuit and when load is removed it causes sparking.
What is an electrostrictive transducer?
any device that converts energy from one form to another usually electrical to mechanical by using the property of all electrical non-conductors, or dielectrics, that causes them to change their shape under the application of an electric field
What does a resistor measures?
Resistors are measured in units of Ohms (Ω).
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
What is the electrical property that opposes change in current?
inductance
What is the ability of substance to slow down the electricity?
The property of a substance enabling it to slow down electricity is called resistance and is measured in ohms. This ability is called electrical resistance. Every substance has this. Gold has the minimum resistance for electricity. Such substance is called electrical conductor. And there are substance where the electrical resistance is affected by heat, light and other conditions. And for those substance where electricity can not flow are called electrical insulators (non-conductors) such as wood and ceramics.
Which metal acts as an insulator?
Metals are conductors, not insulators. Both electrical and thermal conductors.
What has very little resistance to electron flow?
superconductors
Why is electrical conductor important?
Electrical conductors are important because they allow electricity to flow through them with minimal resistance. This property is essential for transmitting electrical energy efficiently, enabling the operation of various devices and systems. Conductors play a critical role in powering our homes, industries, and technology.
What is francium electrical cinductivity?
This property was not measured on francium.
What is francium electrical conductivity?
This property was not measured on francium.
Do all conductors have resistance?
Yes, all conductors have resistance to some degree. Resistance is a property of materials that impedes the flow of electric current. However, some materials have lower resistance (e.g., copper) while others have higher resistance (e.g., rubber).
What is a physicle property that is measured of a solids resistance to being dented?
hardness
What property wire increases when it is made thinner?
electrical resistance
Is electrical resistance and electrical resistivity the same?
No, they are not the same. Electrical resistance is a measure of how much a material opposes the flow of electric current, while resistivity is a property of the material itself that determines its resistance. Resistivity is an intrinsic property of the material, while resistance depends on the dimensions and shape of the material.
What is the correct definition of resistance?
Resistance refers to the opposition a material or object offers to the flow of electric current. It is measured in ohms and is influenced by factors like material composition, length, and cross-sectional area. Resistance is a key property in determining the behavior of electrical circuits.
A conductor with a high temperature is likely to have a high?
Since you are talking about conductors, a high temperature one will have a high resistance. Reason being that the distance between the conduction and the valence band keeps on increasing on the increase of temperature. A substance is said to be conducting if it has FREE electron in its conduction band. Since the distance b.w the to bands increases, less number of electrons are able to jump from valence band to conduction band, hence more resistance...
