Which One is more dangerous: Voltage or Current?

Here is the analogy:-

" Imagine yourself fall down from a very high level of waterfall land then carried away by a very rapid water flows" aren't both situation are dangerous?

The same case as voltage and current. Voltage is dangerous when it is high coz it generates potential. In an open space you cannot go to near to a high voltage installation as you could get a flash over.

As for current even though it is low, it is still dangerous if you come in contact with the conductor coz you will become a pathway for the current to flow through to the earth.
