Question 'I You build a parallel plate capacitor from two 8.30 cm diameter aluminum disks and 0.710 mm rubber spacers. You then connect your capacitor to an ideal battery and, after the capacitor is fully charged, you measure the charge on the positive electrode to be 5.70 nC. What is the emf of the battery? 0 254V 0 34.5 v O 64.7 v O 130. v Question 2 You happen to have three capacitors with values of 8.00 uF, 22.0 pF, and 20.0 pF. If you connect them together in series, what is their equivalent capacitance? O 50.0 pF O 0.0200 pF 0 0.220 uF O 4.54 pF Question 3 To build a capacitor, you use two 6.40 cm x 6.40 cm metal plates for the electrodes and a 0.450 mm thick piece of paper forthe dielectric (with dielectric constant K = 3.7). What is its capacitance? O 0.595 nF O 0.298 nF O 0.397 nF 0 0.0993 nF
