- A parallel plate capacitor is made up of two metal squares with sides of length 7.3 cm, separated by a distance 4.6 mm. When a voltage 139 V is set up across the terminals of the capacitor, the charge stored on the positive plate is equal to nC. Give your answer to 2 decimal places.(a) How much charge is on each plate of a 8.00 µF capacitor when it is connected to a 1.50 V battery? µC(b) If this same capacitor is connected to a 9.00 V battery, what charge is stored? µCStorm clouds build up large negative charges. The charges dwell in charge centers, regions of concentrated charge. Suppose a cloud has -25 C in a 1.0@km@diameter spherical charge center located 10 km above the ground, as sketched is shown. The negative charge center attracts a similar amount of positive charge that is spread on the ground below the cloud.The charge center and the ground function as a charged capacitor, with apotential difference of approximately 4 x 108 V. The large electric field between these two “electrodes” may ionize the air, leading to a conducting path between the cloud and the ground. Charges will flow along this conducting path, causing a discharge of the capacitor—a lightning strike.
