i want to convert 240v ac to 12v dc

i have transformer, bridge rectifier,load

given, load=100ohms, load current=0.12a

peak voltage of secondary=16.970v

rms voltage of secondary=12v

output of bridge rectifier=16.970-1.4=15.57v dc

how can calculate capacitor for circuit plz explain with formula and ripple voltage of capacitor thanks.....
