A microwave is consuming 800 W power using a standard North American 120 V power supply. What is the approximate amount of current flowing?
Detailed Explanation
The formula for finding electrical power is Power = Voltage x Current or P=VI. Rearranged we have \(I= \frac{\mathrm{P} }{\mathrm{V} }= \frac{\mathrm{800} }{\mathrm{120} } = 6.67 \approx 7 \) amperes.
