The capacitance of the parallel combination of C 2 and C 3 is larger than the capacitance of C 2 alone. Since that combination is in series with C 1 , the total capacitance is larger than without C 3 . so q is larger.) b) LEFT (The potential difference across C 1 plus C 2 is the same in both diagrams, it equals E . The potential difference across C 1 is greater in the right diagram, since it carries greater charge. Therefore, the potential difference across C 2 is less in the diagram on the right and greater in the diagram on the left. c) LESS THAN THE CHARGE ON C 1 (The sum of the charges on C 2 and C 3 must equal the charge on C 1 .) 2. a) Apply the right hand rule to each wire, and sum the results. b) Since the currents are parallel, the wire is attracted to the other three....
