I am using voltage regulater IC 7805 to give supply to arduino but it gives higher current supply.I want to know the internal resistance of atmega 328 so that I use resistance in between the digital pin and 7805 to lessen the current

internal resistance of atmega 328

Ohms law really works!

Do you mean: 5V/0.0095A (16Mhz/5V, active mode supply current) = 526ohm
