Question

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.

Answer 1

90J

Step-by-step explanation:

The following data were obtained from the question:

Voltage (v) = 9 Volt

Current (I) = 1 A

Time (t) = 10 secs

Electrical Work =?

Electrical work is given by the following formula:

Electrical work = current x time x voltage

Electrical work = I x t x V

With the above formula, the electrical work can be obtained as follow:

Electrical work = I x t x V

Electrical work = 1 x 10 x 9

Electrical work = 90J

Therefore, 90J of work is done by the battery in 10 seconds
