If you think of a battery as an electric charge "pump" the battery
current is analagous to:
a. rate of fluid flow
b. pressure
c. flow acceleration
d. water
e. none of the above

Hi answer123,

Battery current is analogous to a) rate of fluid flow.

This is because the definition of current is "the quantity of
electrons that flow past a given point in one second". To apply the
water pump analogy, current is "the flow of water past a given point
in one second". Electric current is also a rate, because it measures
the number of electrons that flow over a given period of time.

Just as background information, current = amount of charge / time. The
amount of charge, measured in coulombs, is analogous to the volume of
water flowing through the "pump". Time is measured in seconds. The
unit of electric current is the ampere, or amp.
