How does capacitor store charge from DC source?
We all know that capacitor blocks DC (voltage). I want to know how a capacitor can store charge from DC source? Also, why is DC voltage rating given to the capacitors? Looking forward to answers.

krishna c.r.Capacitor in dc ckt is used to store charge in form of electric field, imagine that we have a
capacitor , a bulb both connected in parallel and also a battery source, now when we close the switch to the battery the capacitor gets charged. then now we open the switch to the battery and close the switch to the bulb then the energy stored in the capacitor immediately dicharges and the bulb glows....

Jeffrey ArulrajThe cap alters from charging and discharging in an AC ckt but in a DC ckt it charges upto the maximum voltage and beyond that point there is no probability of charge to pass or enter through the cap and it becomes open circuited
When we turn the DC source off the stored potential is discharged from the cap -
aruncharycapacitor blocks dc voltage,yes its correct but it happens in series with the circuit, you can check it with placing capacitor in shunt with circuit then it stores electrical energy..
