SUMMARY
The average power in an Alternating Current (AC) circuit is calculated using the formula P = VI, where V represents effective voltage and I represents effective current. In this context, effective voltage and effective current are equivalent to DC voltage and current that yield the same power output. The correct answer to the homework question is option B, which states that average power is equal to VI.
