Resistance is connected in parallel with voltmeter or say, voltmeter is connected in parallel with resistance.
What else can I help you with?
Why does the electrical resistivity of a conductor does not depend on its dimensions?
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length
How do you calculate a cross-sectional area When all you know is resistance resistivity and length?
I think the equation you are looking for is Resistance (ohms) = Resistivity * Length / Area or R=p*L/A. This is the resistance of a circular wire with cross-section of A, length of L, and material with resistivity p. So to get area: Area = Resistivity * Length / Resistance.
What happens to the resistance as the area increases?
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
The resistance of a wire depends on the?
The length, cross-sectional area, and resistivity. As resistivity changes with temperature, temperature indirectly affects resistance.
Which common factor affects both resistance and resistivity and how?
Temperature is a common factor that affects both resistance and resistivity. As temperature increases, the resistivity of conductive materials typically increases due to increased atomic vibrations, which impede the flow of electrons. Consequently, this rise in resistivity leads to an increase in resistance for a given material. Thus, both resistance and resistivity are influenced by temperature, impacting the efficiency of electrical conduction.
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.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
What is the formula for resistivity?
Resistance (Ohms) = Voltage (v) / Current (I)
What is a resistance of a material?
Resistance is the opposition to the flow of electric current. It is affected by the length, cross-sectional area, and resistivity of a material. As resistivity is affected by temperature, temperature indirectly affects resistance.
Three ways which resistance of a wire can be increased?
You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).
What are four factor that determine resistance?
There are three, not four, factors that determine the resistance of a conductor. These are the length of a conductor, its cross-sectional area, and its resistivity.As resistivity is affected by temperature, you could say that temperature indirectly affects resistance but, strictly, temperature is affecting the resistivity not the resistance -which is why it is not considered a 'fourth' factor.So, resistance = resistivity x (length/area)
How resistivity effects internal resistance of a cell experiment?
Resistivity effects internal resistance of a cell experiment by not allowing the cell to react. Internal resistance experiments are performed in advancing physics classes.
