Question

What is the potential difference between the terminals of an ordinary AA or AAA battery? (If you're not sure, find one and look at the label.) Express your answer to two significant figures and include the appropriate units V= 1.5V Previous An swers Correct Part B An AA battery is connected to a parallel-plate capacitor having 2.00-cm-diameter plates spaced 3 mm apart. How much charge does the battery move from one plate to the other? Express your answer with the appropriate units. 4.425. 10 SubmitP Answers Request Answer Incorrect: Try Again; 4 attempts remaining

Explanation / Answer

The formula for capacitence of the parallel plate capacitor is

C = {epsilon 0}. A / d

= 8.85 * 10^-12 ( pi ( 2* 10^-2 m/2)^2 / 0.003

=9.27 * 10^-13 F

for AA battery V = 1.5 V

Q = CV = 9.27 * 10^-13 ( 1.5 V) = 1.39 * 10^-12 C Answer

I hope help you.....
