#### Solution Preview

a) Passive sign convention is when the current through the element flows from positive to negative terminal. Therefore A, C, E, and F are written with the passive sign convention.

b) To determine whether an individual element is ...

#### Solution Summary

This solution is provided in 174 words. It discusses when the passive sign convention is used, and demonstrates how to conclude whether an element is delivering or absorbing power. It then uses this information to find total power.
