Question

Which pair of equations expresses the loop relationship for cells and resistors?

पर्याय

• \[\sum R=\sum E\]

• \[\sum V=\sum I\]

• \[\sum IR+\sum E=0\] or \[\sum E=\sum IR\]

• \[\sum I=0\] or \[\sum E=0\]

Answer 1

The algebraic sum of potential changes in a loop is zero. For a loop containing cells and resistors, the total emf supplied equals the total potential drop across the resistors.
