Problem
During one complete traversal of a closed loop, a charge experiences the following potential changes (in order): +12V, −4V, and −8V. Determine the algebraic sum of these changes and state what additional potential change (magnitude and sign), if any, would be required elsewhere in the loop for the traversal to satisfy energy conservation.
