Homework Statement



A Little power Station uses the water of a Creek. Per second 10 Liters of water fall from a height of 100 meters on the turbine of a power Station. A direct current I = 10 A ist produced. Find the voltage if the Efficiency of the electricity production is 100 %.

Homework Equations



The solution is: 1000 V


The Attempt at a Solution



10 l / s = 10 kg / s

v = J / C

C = 10 C/s

J = ?

How can I calculate the Joule?

Thanks in advance!
