Measuring EMF and Internal Resistance of Dry Batteries Using ESP32 and Phyphox
Recently, inspired by a high school physics exam experiment question, I decided to use the voltage-resistance method to measure the electromotive force (EMF) and internal resistance of a dry battery. A few days ago, I used the ESP32 and Phyphox to measure the EMF and internal resistance of a simulated power supply using the voltage-resistance … Read more
