What statement is true concerning the total power consumed in a series circuit?

ATotal power is the sum of the powers consumed by each load (resistor) divided by the number of loads
BTotal power is never more than the power consumed by the largest load
CTotal power is always less than the power consumed by the smallest load
DTotal power is the sum of the powers consumed by each load
AI Explanation

The correct answer is D) Total power is the sum of the powers consumed by each load. In a series circuit, the total power consumed is equal to the sum of the individual power consumed by each load (resistor). This is because the same current flows through each component in a series circuit, and the power dissipated in each component is proportional to the square of the current and the resistance of that component. By adding up the power dissipated in each load, you get the total power consumed in the series circuit. The other options are incorrect because: A) The total power is not divided by the number of loads. B) The total power can be more than the power consumed by the largest load. C) The total power can be more than the power consumed by the smallest load.
