A 500-W device is connected to a 100-V power source. What current flows through this source? A) 20.0 A B) 1.60 × 10¹⁸ electrons/s C) 200. mA D) 5.00 A E) 50,000 A

Question

Quizplus · Accepted Answer

The current can be calculated using the formula P = IV, where P is power (500 W) and V is voltage (100 V). Rearranging the formula to solve for I gives I = P/V = 500W / 100V = 5.00 A.
