plz....solve this ​

Answer 1

Answer:

ampere is the correct answer mark as brainliest

Answer 2

Answer:

Energy=E=Pt where P=power and t=time

Total energy consumed=E=(60W×5h+100W×3h+1000W×2h)×30

⟹E=(300+300+2000)×30Wh

⟹E=78000Wh=78kWh

We know that 1unit=1kWh

⟹E=78units

Explanation:

Brainliest mark please

Energy=E=Pt where P=power and t=time

Total energy consumed=E=(60W×5h+100W×3h+1000W×2h)×30

⟹E=(300+300+2000)×30Wh

⟹E=78000Wh=78kWh

We know that 1unit=1kWh

⟹E=78units
