Expert Answer:

Yes the capacitor will shows a momentary deflection. And after some move to zero when the capacitor gets fully charged. 

 Let the capacitor is charging with the help of resistance R.

Time constant of changing,

This is the expression for current at different time. 

i tends to zero with time.
