Which of the following equations represents the Ampere-Maxwell law? |
$\int B.dA = 0$ $\int E.dA = Q/ε_0$ $\int E.dl = -d\phi_B/dt$ $\int B.dl = μ_0i_c+μ_0ε_0d\phi_E/dt$ |
$\int B.dl = μ_0i_c+μ_0ε_0d\phi_E/dt$ |
The correct answer is Option (4) → $\int B.dl = μ_0i_c+μ_0ε_0d\phi_E/dt$ The Ampere-Maxwell law relates the magnetic field around a closed loop to the conduction current and the displacement current passing through the loop: $\oint \vec{B} \cdot d\vec{l} = \mu_0 i_c + \mu_0 \epsilon_0 \frac{d\Phi_E}{dt}$ |
