Question 91

Multiple Choice

A comparison of the power losses P<sub>1</sub>, P<sub>2</sub>, or P<sub>3</sub>) in the resistors of the circuit in the diagram shows that, if R<sub>1</sub> = R<sub>2</sub> = R<sub>3</sub>, A) 4P<sub>1 </sub>= P<sub>2 </sub>= P<sub>3</sub>. B) P<sub>1</sub> = 2P<sub>2</sub> + 2P<sub>3</sub>. C) P<sub>1</sub> = P<sub>2</sub> = P<sub>3</sub>. D) P<sub>1</sub> = 1/2) P<sub>2</sub> = 1/2) P<sub>3</sub>. E) P<sub>1</sub> = P<sub>2</sub> + P<sub>3</sub>.<sub> </sub> A comparison of the power losses P1, P2, or P3) in the resistors of the circuit in the diagram shows that, if R1 = R2 = R3,
