I want to know how acapacitor on parallel line smoothes the vdc output after arecitifier. Shouldn't it better be put on a serial line.please i need to have an explaination to the mechanism of capacitor operating in this circuit

Have a look at this link, come back and ask questions.

Best link I could find to visualize whats going on.
Full-Wave Rectifier w/ Filter

The parallel cap charges up till the peak of the DC wave then discharges as the wave's output falls helping to smooth out the output.

the output after the full wave rectifier bridge is DC with a ripple so, we can't put the capacitor on serial because the output will be zero volt.

connecting a capacitor between the input and ground will ground any AC component of the signal, in DC power supply, this AC component represent noise or harmonics..so by connecting capacitor in this way, it will create a more constant output voltage.

certain value of capacitor will filter out certain value of unwanted AC component or noise, thus by connecting different values of cap in parallel(in resistor sense) will give more constant DC.

wish my explanation is correct and help u
