Which statement is true concerning the total power consumed in a parallel circuit?

AThe total power is never more than the power consumed by the largest load.
BThe total power is the sum of the powers consumed by each load (resistor) divided by the number of loads.
CThe total power is always less than the power consumed by the smallest load.
DThe total power is equal to the sum of the powers consumed by each individual load.
AI Explanation

The correct answer is D) The total power is equal to the sum of the powers consumed by each individual load. In a parallel circuit, the total power consumed is the sum of the power consumed by each individual load (resistor). This is because each load in a parallel circuit has its own path for current to flow, and the power consumed by each load is independent of the others. Therefore, the total power consumed is the algebraic sum of the power consumed by each load. The other options are incorrect because: A) The total power can exceed the power consumed by the largest load, B) The total power is not divided by the number of loads, and C) The total power can be greater than the power consumed by the smallest load.
