Can we give any desired charge to a capacitor?

Can we give any desired amount of charge to a capacitor?

Can we give as much charge to a capacitor as we wish?

The charge on capacitor is

The charge on the capacitor is

Charging of Capacitor

As we know in steady state charge on a capacitor is given as Q= CV which also implies C= Q//V . So can we say in steady state capacitance is proportional to the supplied charge Q .

What is net charge on a charged capacitor?

What is the net charge on a charged capacitor?

In an L-C oscillation maximum charge on capacitor can be Q_0 . If at any instant electrical energy is the 3/4 of the magnetic energy then the charge on capacitor at that instant is
