DC circuitsQuestion 329 of 1506

After a series-parallel circuit has been solved, how can you check the branch currents?

  1. The branch currents of a parallel group add to the total
  2. Each branch should carry the total circuit current
  3. The branch currents should all be equal in value
  4. The branch currents should multiply to the total
Show answer

Correct answer: The branch currents of a parallel group add to the total

Parallel branch currents add to the current that enters the group.
