Power:

$\overline{){\mathbf{P}}{\mathbf{=}}{\mathbf{i}}{\mathbf{V}}}$

**a)**

The unit of current, Amperes, is Coulombs per second.

The rate of change, C/s is the same as A.

A 1.5 V battery provides 0.54 A of current.

a) At what rate (C/s) is charge lifted by the charge escalator?

b) How much work does the charge escalator do to lift 1.0 C of charge?

c) What is the power output of the charge escalator?
