## Homework Statement

The engine delivers 12 kW. Per second it can shift the m = 800 kg car over a vertical distance of 1.5 m. Find the current delivered by the batteries.

## Homework Equations

P = U * I

I = P/U = 12 000 W /

**168 V**= 71.4 A

## The Attempt at a Solution

My Problem is: I don't really know how to calculate V...

I know that V = J/C and Js = 12 000, but I don't know how to find out the Coulomb.

Can please someone help?
