how does capacitor oppose sudden chane in voltage?
how does inductor oppose sudden change in current?
Answer Posted / sabaris
Generally capacitors stores the energy as voltage in magnetic field..the stored energy is directly proportional to the area and inversly proportional to the distance btwn the two metals...these two things are constant.already it charges in a linear time and discharging it in some linear time..if a sudden change will occur(i.e. vge raise or drop) there is no possibility to charge are discharge with respect to it..thats why capacitor always dont allow the sudden changing voltages...in inductor it stores the energy as current in electric field...similarly the procedure is above the same....
