JEE Main 2025 — 7 April, Morning Shift — Question 56

If ∈o\in_{o} denotes the permittivity of free space and ϕE\phi E is the flux of the electric field through the

area bounded by the closed surface, then dimensions of (ϵ0dϕEdt)\left(\epsilon_{0} \frac{d \phi_{E}}{d t}\right)

are that of:

  1. Option A:

    electric current

    Correct
  2. Option B:

    electric charge

  3. Option C:

    electric field

  4. Option D:

    electric potential

Answer: A

Step-by-step solution

Dimension of ϵ0(dϕEdt)\epsilon_{0}\left(\frac{d \phi_{E}}{d t}\right) will be Same as electric

current So [ϵ0dϕEdt]=A\left[\epsilon_{0} \frac{d \phi_{E}}{d t}\right]=A
