Question
Several 10 W bulbs designed for 220 V are connected in parallel to a 220 V line with maximum allowable current of 5 A. The maximum number of bulbs that can be connected is:
10
50
110
220
Answer
220
Detailed Explanation
Current per bulb = P/V = 10/220 A. Max bulbs = 5 / (10/220) = 5 x 220/10 = 110.
