Question

several electric bulbs designed to be used on a 200 V electric supply line are rated 11 W each . how many bulbs can be connected in parallel with each other across the two wires of 220 V line if the maximum allowable current is 5 A ?​

✶ Given,

Power (P) = 11W

Electric Voltage (V) = 220V

Electric current (I) = 5A

Let "n" is the number of bulbs

Then,

we know....

P = VI

so, I = P/V

=> 11/220

=> 1/20

If "n" is the number of bulbs connected in parallel, then total current in the circuit would be -------------

(1/20)n

But current is giver in the question, that is 5A .

So, Equate both electric current......

=========> (1/20)n = 5

=========> n = 5 * 20

=========> n = 100

★ So, the number of bulbs would be 100, which is connected in parallel.★
