An electric bulb is rated as 10 W, 220V. How many of these bulbs can be connected in parallel across the two wires of 220 V supply line if the maximum current which can be drawn in 5A ?

Question

Philoid · Accepted Answer

Here it is given P = 10W, V = 220V, I = 5A

As we know that

P = VI

= 220X5

P = 1100W

Power of one bulb = 10W

So the total no. of bulbs that can be connected = 1100/10 = 110
