This is College Physics Answers with Shaun Dychko. The pocket calculator has a 1.35 volt battery and the current flowing through it is 0.2 times ten to the minus three amps. So resistance is voltage divided by current, so 1.35 volts divided by 0.2 times ten to the minus three amps gives us 6750 ohms.
