Calculate the terminal voltage of a 5.9500 V lithium cell in a digital wristwatch that draws 0.4900 mA and the cells internal resistance is 6.9500 Ω. Answer should be in the correct number of sig. figs. .
Homework Answers
V = E - I r = 5.9500 - 0.4900 × 6.9500 × 10-3
V = 5.9500 - 3.4055 × 10-3
V = 5.9466 volt
