diode is a unidirectional device i.e when connected in
forward bias it conduct and in reverse bias it does not
conduct also it converts AC to DC.

capacitor when connected in circuit does not allow current
to flow if it is fully charged.
it has a property to store energy.
capacitor when discharged gives waveshape similar to that
of dc.
