Question

two toungsten bulbs of power 50w and 60w work on 220v potential difference. if they are connected in parallel how much current will flow in the main conducter​

Answer 1

Explanation:

Given: P1= 50W

P2= 60W

P3= 100W

To find: I = ?

Solution :

Power= V × I

P1= V × I1

50 = 220 × I1

I1 =0.227 A

Similarly,

P1= V × I2

60 = 220 × I2

I2= 0.27 A

The two bulbs are connected in parallel

The two bulbs are connected in parallel therefore,

I = I1 + I2

I = 0.227 + 0.27

I = 0.497 A

Answer:

0.497 A current will flow in conductor.
