Abstract
We calculate the effective Komar conserved quantities for the dimensional charged Myers-Perry spacetime. At the event horizon we derive a new identity where the left hand side is the Komar conserved quantity corresponding to the null Killing vector while in the right hand side , are the black hole entropy and Hawking temperature. From this identity we also derive the generalized Smarr formula connecting the macroscopic parameters , , of the black hole with its surface gravity and horizon area. The consistency of this new formula is established by an independent algebraic approach.
