The SI unit of the current density is __________.
- A \(Am ^{-1}\)
- B \(Am ^2\)
- C \(Am ^3\)
- D \(Am ^{-2}\)
Answer & Solution
Correct Answer
(D) \(Am ^{-2}\)
Step-by-step Solution
Detailed explanation
(D)
Current density \(J =\frac{ I }{ A }=\frac{ A }{ m ^2}\)
\(= Am ^{-2}\)
Current density \(J =\frac{ I }{ A }=\frac{ A }{ m ^2}\)
\(= Am ^{-2}\)
