What else can I help you with?
Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
What is the internal friction that hinders the flow of electrons through any material?
Internal friction created because the electrons hit the various metal's latices or atoms. Higher the temperature more movements so the possibility of hitting is higher so more resistance to flow
What is the value of internal impedance of ideal current source?
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
What is difference between ideal current source and practical current source?
Internal resistance. The ideal current source has no internal resistance in parallel with it (if it was set to supply no current it would act as an open circuit), and all the current it supplied would have to flow through its load (even if the load was an open circuit, in which case the voltage across the current source would be infinite). A real current source has the practical limitation that it must have an internal resistance in parallel with it, therefor some of the current it supplied is bypassed through that internal resistance and never reaches the load (if the load was an open circuit, then all the current supplied is bypassed and the resulting voltage drop across the internal resistance limits the voltage across the current source).
Does water decrease a substance resistance to the flow of electricity?
Water can increase a substance's conductivity, making it easier for electricity to flow through. This is why water can decrease a substance's resistance to the flow of electricity.
Define Internal Resistance?
The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.
What is meant when a substance is described as having a low resistance?
A substance with low resistance allows easy flow of electric current through it. It means that the substance does not impede the flow of electrons, resulting in efficient conduction of electricity. Materials like metals typically have low resistance.
What is the relationship of internal friction and viscosity?
yes
Can Water can decrease a substance resistance to the flow of electricity?
Reduce the temperature of the conductor.
What is the tendency of a substance to resist the flow of electrons?
That tendency is known as electrical resistance. It is a measure of how difficult it is for an electric current to pass through a substance. Materials with high resistance impede the flow of electrons, while materials with low resistance allow electrons to flow more easily.
What do you call a substance that offers resistance?
A substance that offers resistance is called a resistor. It is a component in electronic circuits that limits or controls the flow of electric current.
How is viscosity related to flow rate?
Viscosity is a substances resistance to flow. So as the viscosity of a substance increases, the flow rate will decrease.
What is the degree to which a substance resists flow known as?
For resistance to electrical flow, the term is specific resistance of a substance.The resistance of a fluid (gas, liquid) to flowing is called its viscosity, referred to colloquially as its thickness.
What is the relation between viscosity and flow ability of a material?
The higher the viscosity, the lower the flow-ability of a material.(Viscosity=internal resistance to flow)
What information does the battery internal resistance chart provide?
The battery internal resistance chart provides data on how much resistance the battery has to the flow of electricity within it. This information can help determine the battery's efficiency and performance.
Why is Substance B more viscous than substance A?
Substance B may be more viscous than substance A due to a higher molecular weight, stronger intermolecular forces, or a more complex molecular structure. These factors can lead to increased resistance to flow and greater internal friction within the substance, resulting in higher viscosity.
