Capacitor Charging With Rc Circuit

about this video-
in this video I explain you about capacitor charging with the help of rc circuit.how capacitor is charged through rc circuit and what happens to current and voltage in circuit as the time progresses and i also explain you why resistance is used in capacitor charging circuit and why capacitor is only charged with dc source.and why there is no voltage developed across the circuit when battery is not connected to it and how voltage is developed across capacitor when voltage sorting is connected across the capacitor. and why initial value of current is high in rc charging circuit.
