  We obtain some exact results for black holes in the Randall-Sundrum model
with a single brane. We consider an extreme black hole charged with respect to
a Maxwell field on the brane. The near-horizon geometry is determined. The
induced metric on the brane and the black hole entropy are compared with the
predictions of 4d General Relativity. There is good agreement for large black
holes, with calculable subleading corrections. As a separate application, the
bulk solution provides a gravitational dual for (strongly coupled, large N) N=4
SYM in AdS(2)xS(2) for arbitrary relative size of AdS(2) and S(2).
