"charging and discharging of capacitor ''
Is this topic include in physics board syllabus of 2019-20.?
Don't give wrong answers.

yes this is included and here is the meaning of this system--
Capacitors are simply energy storage device.
Let a capacitor is connected to a dc voltage source in series. Initially charge on capacitors plates is zero. when connected to dc supply current flows and charge begins accumulating on the plates.
Suppose the dc supply voltage is V. and voltage on capacitor at any time t be Vc.
Since charge is accumulating on the plates.We know that Q = C*Vc.
where
Q = charge on capacitor.
C= capacitance.
Once voltage on capacitor becomes equal to supply voltage i. e. Vc=V ,voltage difference between supply voltage source and capacitor becomes zero. And circuit becomes open.We say capacitor is charged.
Now we remove supply voltage source from the circuit and add external device say led bulb in series with charged capacitor. Now the capacitor acts as voltage source and current flows in the circuit until the voltage on the capacitor becomes zero again.This is called discharging.
hope it helps
