What is required for an electric charge to flow through a wire? zero resistance in the wire a balance of electric potential high resistance in the wire a difference in electric potential

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

Select all the correct answers.which two statements are true? a moving magnetic field creates an electric field.a constant magnetic field creates an electric field.a constant electric field creates a magnetic field.a moving electric field creates a magnetic field.resetnext
