Incorrect Formula for J:
There are various formulae used in electrical engineering, and it is important to ensure that the correct formula is used to calculate quantities accurately. In this case, the formula that does not account for the correct expression for J is the one denoted by option 'D', which is μH.
Explanation:
- The correct expression for electric current density (J) is given by J = σE, where σ is the conductivity of the material and E is the electric field.
- Option 'A' (ρv) and option 'B' (I/wd) do not represent the correct expression for J either.
- Option 'C' (σE) is the correct expression for J, where σ is the conductivity of the material and E is the electric field.
- However, option 'D' (μH) represents the magnetic field intensity, not the current density.
Therefore, the formula μH does not account for the correct expression for J because it represents a different quantity in the context of electrical engineering. It is essential to use the accurate formulae in calculations to obtain precise results in the field of electrical engineering.
