When a 10 ohm load is placed across the terminals of a battery, the terminal voltage is 11.0V. When a 100 ohm load is used instead, the terminal voltage is 11.9V. What is the internal resistance of the battery?
2. Relevant equations
3. The attempt at a solution
I do not know how to approach this question but I do know that I have to use V = IR. I also know that the terminal voltage occurs after the voltage drop from the internal resistance. Is this right? A hint on how to approach this question would be nice! Thank you
