Question

The maximum current which can be drawn from a circuit is 6 A. How many 20 W bulbs rated at 220 V can you connect in parallel between a line having a voltage difference of 220 V?​

Answer 1

Answer:

Step-by-step explanation:

P=20W,V=220V,I=6A

We know that power is given as:

P=VI

=220×6

P=1320W

Power of one bulb =20W

Total no. of bulbs that can be connected =1320/20=66

Answer 2

Power of one bulb (P) = 20W

V = 220V

I = 6A

➻ P = 220 x 6

➻ P = 1320W

↳ This is power of n number of bulbs.

so,

No.of.bulbs connected is

➻ 1320/20

➻ 66 bulbs
