Question

Two electric bulb of 100w and 200 w are connected in parallel with a source of 220v.Find the total
cu.ront drawn by these bulbs.​

Answer 1

Answer:

Given : power1=100w and power2=200w

and potential difference=220v

so, p1+p2=100w+200w=300w and p.d=220v

P=VI (formula)

300=220×I

30/22=I

I=1.66(app.)

so total current by both bulb is 1.67 ampere
