What is the Resistance of Your Calculator?

[zapped]

Homework Statement

a battery delivers nearly constant voltage of 1.5 V and stores about 10^4 joule of energy.

Homework Equations

From time it takes you to use up the batteries in your calculator estimate the resistance of your calculator.

The Attempt at a Solution

I really don't know the equations I need for this question, this was a review problem set from gr.11. I don't have the gr.11 physics textbook and it's not on the gr12 textbook.

Please post the equations I need for this question, thanks!

They give you total energy. That's Joules.

If you divide by the total time, J/s - watts.

Watts is V*I and you have V, so you can figure I.

And V = I*R

gives you R.
