There is no 'formula' for resistivity. The resistivities of different conductors have been determined by experiment.
Resistance (Ohms) = Voltage (v) / Current (I)
L1-L0=(RESISTANCE*AREA)/RESISTIVITY where L1=INIIAL LENGTH and L2=FINAL LENGTH
Yes, resistivity depends on the length and cross-sectional area of the material. Resistivity is calculated using the formula ρ = R(A/L), where ρ is the resistivity, R is the resistance, A is the cross-sectional area, and L is the length of the material.
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
R is the electrical resistance,A is the cross-sectional area,l is the length of the piece of material.
Yes, resistivity does depend on the dimensions of the conductor. The resistivity of a material is an intrinsic property, but the resistance of a conductor is also influenced by its dimensions such as length, cross-sectional area, and shape. These dimensions affect the resistance of the conductor through the formula R = ρ * (L/A) where ρ is resistivity, L is length, and A is the cross-sectional area.
The resistivity of the material can be calculated using the formula: resistivity = resistance x cross-sectional area / length. Plugging in the values: resistivity = 20 ohm x 2 cm / 10 cm = 4 ohm cm. Since resistivity is measured in ohm meters (SI unit), the resistivity of the material in SI unit would be 0.04 ohm meter.
R= ρL/A ρ- electrical resistivity of the materialL- length of the conductor.A- cross sectional area of the conductor.
Take measurements of resistances of various lengths of a wire of constant diameter. Make a graph of resistance against length / cross-sectional area of wire. The gradient of the straight line section will be equal to the resistivity of the wire.
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
Oh, dude, it's like this: to convert conductivity to resistivity, you just take the reciprocal of the conductivity value. So, resistivity is equal to 1 divided by conductivity. It's like flipping a coin, but with numbers. Easy peasy, right?
