- Homework Statement
- A battery of emf E and internal resistance r is hooked up to a variable "load"

resistance, R. If you want to deliver the maximum possible power to the load, what resistance

R should you choose?

- Relevant Equations
- Ohms Law V = IR

I equated dP/dR to 0 and find the solution for R. Is the solution correct?
