Capacitance Charge Potential difference Energy 0.0016 C 0.013 J 2. Ten identical 6 /F capacitors are connected in parallel to a 240-V battery. The charged capacitors are then disconnected from the battery and reconnected in series, the positive terminal of each capacitor being connected to the negative terminal of the next. What is the potential difference between the negative terminal of the first capacitor and the positive terminal of the last capacitor? 4. Lightning is a spectacular example of electric current in a natural phenomenon. There is much variability to lightning bolts, but a typical event can transfer 10" J of energy across a potential difference of perhaps 6 x 10' V during a time interval of about 0.3s. Use this information to estimate the total amount of charge transferred, the current, and the average power over the 0.2s. A copper wire 3.2mm in diameter carries a 5.0A current. Determine (a) the current density in the wire
