Current Density Formula

In the field of electromagnetism, Current Density is the measurement of electric current (charge flow in amperes) per unit area of cross-section (m2). This is a vector quantity, with both a magnitude (scalar) and a direction. J = I/A J = current density in amperes/m2 I = current through a conductor, in amperes A = cross-sectional area of the conductor, m2 Current Density Formula Questions: 1) A current of 6 mA is flowing through a copper wire that has an area of 4 mm2. What is the current density? Answer: The…
