WebStudents will be asked to look up the resistivity of the metal of their wire. It is useful to have a data book or internet access available (and to know the metal being used). Expected … WebHigh values of resistivity imply that the material making up the wire is very resistant to the flow of electricity. Low values of resistivity imply that the material making up the wire transmits electrical current very easily. The unit of resistivity is the ohm meter (Ω m). The resistivity ρ (rho) of a material is given by
Resistance of a Wire - GCSE Science Required Practical
WebPlan of the method to be used:- The resistivity of a wire can be determined using the equation P= RA/L Where: R:- Is the resistance of the wire in ohms and can be determined using the equation R=V/I where V is voltage in volts and I is current in amperes. L:- is the length of the wire used in metres. A: - Is the cross-sectional area of the WebI cannot really predict the outcome of my experiment but I will take 2 readings of voltage and current as I assume the wire will heat up and affect the readings as the experiment goes … cny boys high school basketball
Experiment 1 - abc - Aim: To determine the resistivity of two/three ...
WebElectrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ ().The SI unit of electrical resistivity is the … WebA student wants to find the resistivity of a constantan wire. They set up the experiment by attaching one end of the wire to a circuit with a 6.0 V battery and the other with a flying lead and measure the length with a ruler. Attaching the flying lead onto the wire at different … WebThe ammeter reading was adjusted to 0.10 A by adjust the rheostat. After the rheostat was adjusted, the switch button was pressed to allow the current flow in the circuit. The … cny brain \\u0026 spine
