The pointed tip results in a concentrated electric field around the tip when the rod is grounded , this makes the lightning more likely to strike the rod rather than some other nearby non-sharpended object.

stunning, shall we get somewhat technology going right here and decrease during the myths. Lightning conductors at the instant are not positioned up to get hit via lightning as such. they are in a position to and do get hit via lightning however the expression "conductor" is a misnomer. They act as a discharge to floor to ward off the accumulation of static value in an approximate "sphere" from the top of the rod to the encircling floor. Any lightning strike could have a tendency to pass around the exterior of this sphere and grant safety for the people under the sphere. for this reason status close to the tall development frequently supplies finished safety. The taller the development the extra effectual and wider is the safety

Before lightning strikes it measures the lowest resistive path from where it is to the ground.
At the height level the point is, that surface area becomes the lowest resistance straight to ground for an area encompassed by a 30 degree cone to earth.
It stops wasting its energy zig-zagging around the sky and earths itself.

The reason why the lightining conductor is pointed is to enable fastest access of lightning substance

another common sense answer is to keep the birds from resting on them. bird droppings can effect their efficency.
