Q19. In Ampere-circuital law, the missing term is:
(a) i = ερ dΦ_E / dt
(b) i = ε dΦ_E / dt
(c) i =

Q: What is the correct answer for CUET UG Physics Q19?

The correct answer is b. Ampere's Circuital Law was modified by Maxwell to include the concept of displacement current (I_d) to ensure consistency with the continuity equation for current. The generalized Ampere-Maxwell law states: ∮ **B** ⋅ d**l** = μ₀ (I_c + I_d), where I_c is the conduction current and I_d is the displacement current. The displacement current (I_d) is given by the rate of change of electric flux (Φ_E)

Ampere's Circuital Law was modified by Maxwell to include the concept of displacement current (I_d) to ensure consistency with the continuity equation for current. The generalized Ampere-Maxwell law states: ∮ **B** ⋅ d**l** = μ₀ (I_c + I_d), where I_c is the conduction current and I_d is the displacement current. The displacement current (I_d) is given by the rate of change of electric flux (Φ_E) through a surface, multiplied by the permittivity of free space (ε₀). So, I_d = ε₀ (dΦ_E / dt).Given the options, option (b) `i = ε dΦ_E / dt` represents this displacement current, assuming 'ε' is used interchangeably with 'ε₀' (permittivity of free space).
