Now find an expression for Bdl, the same line integral of B around the same loop of radius R located just outside the left capacitor plate as before. Use the surface that passes between the plates of the capacitor, where there is no conduction current. This should be found by evaluating the amount of displacement current in the Ampère-Maxwell law above Learning Goal To show that displacement current is necessary to make Ampère's law consistent for a charging capacitor (Figure 2) Ampère's law relates the line integral of the magnetic field around a closed loop to the total current passing through that loop. This law was extended by Maxwell to include a new type of "current" that is due to changing Express your answer in terms of the electric field between the plates E(t), dE(t)/dt, the plate area A, and any needed constants given in the introduction electric fields: $ B-di-?0(!charge t.
