A parallel plate capacitor of plate area A each and seperation d , is being charged by an ac source Show that the displacement current inside the capacitor is the same as the current charging the capacitor(CBSE 2019) . Answer: `I_d`=`epsilon_0frac{dphi_E}{dt}` `I_d`=`epsilon_0frac{d(E.A)}{dt}`--------------(1) Q=CV V=Ed `therefore` E.A `=frac{(Q A)}{Cd}` C=`epsilon_0frac{A}{d}` `therefore` E.A `=frac{Q}{epsilon_0}`(also by Gauss's Theorem) substituting in (1) `I_d`=`frac{dQ}{dt}` ie `I_d`= I
