C1 has capacitance of 0.05 μF C2 has capacitance of 0.1 μF C1 fully charged, connected to a 0.4 V battery C2 left uncharged. C1 was disconnected from the battery and two parts joined, allowing the charge to transfer from C1 to C2. Q: Calculate the percentage of charge transferred from C1 to C2. I've calculated the charge on C1, from using Q = CV, as 2x10^-8 C I'm unsure how to calculate C2 or a percentage of charge transfer. Thanks in advance.
