I need to know how many 15W bulbs can be connected in parallel If I use an extension cord in the 5A socket? If I use the 15 A socket then how many bulbs can I connect in parallel?
Assuming the voltage to be 220 V,
The current drawn by a single bulb is 15/220=0.068 A
So the no. of bulbs which can be connected in parallel = 5/.068=73 (avoiding the fractional part)
If you use 15A, then 220 bulbs can be connected. (follow the same procedure)
