The individual caught the wire of a copper electronic line. He wasn't electrocuted, although being in contact with an exposed live wire. The wire was able to reduce his speed before finally hitting the ground. Create a scientific explanation if such an event is possible or not.A student woants to identify the Resistivity of a conducting wire of unknown material. Resistivity is a property of a material that quantifies how strongly it conducts electric current, and it is formulated as, of p= R4 where R is the Resistance (ohms), A cross-sectional area (meters-squared) and I is the length (meters) of the wire. The student runs an experiment on a cylindrical wire of a length l of 2 centimeters and the cross- sectional area A of the wire is 6.1 centimeters-squared. The measurements of the Current is as below Dataset Voltage (Applied, Volts) Current (Measured, Amperes)
- If the cable wire of my charger is damaged exposing the copper wire, I should cover it with electrical tape because, * The electrical tape is a conductor, thus it will prevent the flow of electricity from the copper wire which is a conductor as well. The electrical tape is an insulator, thus it will prevent the flow of electricity from the copper wire which is an insulator as well. The electrical tape is a conductor, thus it will prevent the flow of electricity from the copper wire which is an insulator. The electrical tape is an insulator, thus it will prevent the flow of electricity from the copper wire which is a conductor.A.
