Several electric bulbs designed to be used on a 220 V electric supply line, are rated 10 W. How many lamps can be connected in parallel with each other across the two wires of 220 V line if the maximum allowable current is 5 A?
Answers (1)
Given: V=220V and P=10W
Let x be the number of bulbs.
I = 5A and V=220V
For x bulbs of resistance 4680 Ohm, are connected in parallel to obtain 44 Ohm equivalent resistance.
Thus,
Hence, 110 bulbs of 4840 Ohm are connected in parallel to obtain 44 Ohm
