1. The problem statement, all variables and given/known data An external circuit with a total series resistance of 50 (omega) is connected to a 1.5 V AA battery which has an internal resistance of 1 (omega). What is the battery’s terminal potential difference? 2. Relevant equations I = EMF / (R + r) 3. The attempt at a solution I = EMF / (R + r) = 1.5V/ 51 Ohm = 29.412 mA V = 1.5V - 0.029412A * 1 Ohm = 1.47 Volt but i m still confused if i did it right or wrong please help Thank you!
