Hi Chirag,
There are lots of things wrong with that drawing!
Assuming the 240VAC is the input, the bridge rectifier is not oriented correctly, the inputs and outputs are mixed up!
Assuming the rectifier fault is corrected, you are going to get DC voltage on that 10uF filter capacitor.
A transformer does not work with DC voltage/current!
You need to put the transformer at the AC input of the circuit to achieve isolation and still have functionality.
But to start with, you need to specify the requirements, like output voltage, current, e.t.c.
