- Current density is defined as the amount of electric charge flowing across a unit cross-sectional area in unit time.
- It is a vector quantity.
The electric current density (J) for a given conducting material is given as:
\(J = \frac{q/t}{A} = \frac{I}{A}\)
Where q is the electric charge flowing, t is the time, I is the current flowing and A is the cross-sectional area.
EXPLANATION:
- The SI units for current and area are A and m2 respectively.
Current density, \(J = \frac{I}{A}\)
- Thus, the SI unit of current density is A/m2.
- Hence option 3 is correct.
