Why does no current flow in a capacitor in steady state
When a capacitor is fully charged in steady state, there is no current flow through it because the capacitor has stored maximum charge on its plates, resulting in equal and opposite charges on each plate. ... In this condition, the electric field between the plates is strong enough to maintain the voltage across the capacitor without the need ...
voltage
The initial voltage across the capacitor would be 0V (uncharged). The initial current would be limited by the resistance (R) and the supply voltage (10V) just like any other RC circuit, (I = 10/R amps) but as C is infinitely large (infinite time constant) the voltage across its plates will never rise and remain at 0V. The circuit will effectively act …

For capacitor ic(t)=C *dvc(t)/dt, when switch is closed there is voltage difference between the +ve and -ve terminal. Hence, there will be flow of current until cap is charged. Since battery is a constant voltage source, the cap will be charged to 10 V and after that there …

In steady state, the net change over one switching period of the capacitor voltage must be zero, so that the left-hand side of Eq. ( 2.26 ) is equal to zero. Therefore, in equilibrium the integral of the capacitor current over one switching period (having the dimensions of amp-seconds, or charge) should be zero.
