Problem

In a closed circuit, a group of charges with a net charge of 2.0 C collects near the negative terminal of a cell. The cell spends 6.0 J of energy on the charges.
After which, the energized charges move out from the positive terminal of the cell and rejoin the circuit.
What is the voltage, Vcell, supplied by the cell?
Vcell=
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
