SUMMARY
The discussion centers on calculating the charge transferred by a 1.5 V AA battery connected to a parallel-plate capacitor with 6.00 cm diameter plates spaced 4 mm apart. The capacitance (C) was calculated using the formula C = Aκε/d, resulting in a value of 1.99 x 10-12 F. The charge (Q) was then computed using Q = V * C, but the initial calculation was incorrect due to the omission of the π factor in the area formula. Correcting this error is essential for accurate charge determination.
