Which of the following is NOT a correct formula for calculating power?
A) P = V2/R
B) P = IV
C) P = I2R
D) P = VR

Question

Quizplus · Accepted Answer

Power in electrical circuits is correctly calculated using three main formulas: P = IV (where P is power, I is current, and V is voltage), P = I^2R (where R is resistance), and P = V^2/R. The formula P = VR is incorrect because it does not account for the relationship between power, voltage, and current correctly. Power is the product of current (I) and voltage (V), not voltage and resistance (R).
