Is there any formula to calculate the maximum current that flow through the conductor …

Any standards for the current flowing?

Typically the concern with max current through a cable is that the insulation on the wire or cable will breakdown as the cable gets hot.

Is there a particular cable that you are analyzing?

Thanks for Your reply

Im looking for the standard Formula.

Suppose Example: PVC insulated copper cable of 2.5 sq-mm .

According to standard the value is 2.5 sq-mm maximum current we have to consider during the circuit design is 15 Amps.
