## Homework Statement

There is a battery producing emf

*and the current around the circuit is*

**V***The battery has an internal resistance of*

**I.***. What is the power transformed by the battery*

**R**## Homework Equations

P = VI

P= I

^{2}R

## The Attempt at a Solution

Maybe P=VI+I

^{2}R because there is some electrical energy converted in the cell resulting in the power

**And then the same power is used to create power**

*VI***in the internal resistance.**

*I*^{2}RSo shouldn't it be the sum of the two powers because it is the total power transformed.
