Answer:
Energy consumed in 2hrs= 1kWh
Energy consumed in 1hr= 0.5kwh
So,
1kWh=3.6×10^6j
0.5kWh=1.8×10^6j
Therefore
Energy consumed in 2hrs = 2×1.8×10^6j =3.6×10^6j
Answer:
3.6 x10^6 j
Explanation:
Energy consumed in 2 hrs= 1 kWh
Energy consumed in 1hr= 0.5kwh
So,
1kWh-3.6x10 6j
0.5kWh=1.8*10^6j
Therefore
Energy consumed in 2hrs 2x1.8x10^6j
3.6x10 6j
