Question 4

 * What happened to the voltage?


 * As you are given the charge is 1mC and the capacitance is 2mF, you could work out the voltage if you were interested. The stored energy can be calculated from just the charge and the capacitance, so the voltage is incidental. Recent Runes (discuss • contribs) 00:44, 29 November 2012 (UTC)
