If the electric field as a function of time inside the capacitor is E(t) = Eocos(wt), find: a) The magnetic field magnitude & direction) at any distance r from the wire (far away from the capacitor). b) The charge on the capacitor as a function of t (the capacitance of a parallel plate...
An 18.1v voltage source charges a capacitor that has circular plates with a radius of 4.4 cm, which is in series with a resistance of 6.36Ω. If the separation between plates is 9.35 mm, what is the magnetic field between the plates? 2.25 cm from the center when t = 2RC? To achieve this, calculate the electric flux, consider that for a parallel plate capacitor the electric field E = ε0 σ and σ is the surface charge density σ...
