When a capacitor is connected to a battery,
(a) An alternating current flows in the circuit.
(b)No current flows at all.
(c) A current flows for some time and finally it decreases to zero.
(d)Current keeps on increasing and reaches maximum after some
time.
Dear Student
If an uncharged capacitor C is connected across the terminals of a battery of potential V then a current flows as the capacitor plates get charged.
The current stops flowing as soon as the charge Q on the positive plate reaches the value Q=CV.
When charge reaches the value Q=CV , the electric field between the capacitor plates cancels the effect of the electric field generated by the battery, resulting in no further movement of charge.
Therefore a capacitor when connected across battery, first current flows reach to maximum then remain steady.
Hence correct option is d.
