Question
An electric lamp (100 ohm), a toaster (50 ohm), and a water filter (500 ohm) are connected in parallel to a 220 V source. Which appliance draws the most current?
The lamp (100 ohm)
The toaster (50 ohm)
The water filter (500 ohm)
All draw equal current
Answer
The toaster (50 ohm)
Detailed Explanation
Lower resistance draws more current at the same voltage (I=V/R); the toaster has the lowest resistance (50 ohm), so it draws the highest current.
