If the current flowing into and out of a 9 Volt battery is 1 Ampere, how much work is done by the battery in 10 seconds?

that potential difference has units of Volt and 1 Volt = 1 Joules/Coulomb.
A Volt represents the amount of work (in Joules) required required to move a charge through a potential difference.
