Answer : The energy consumed by bulb in 24 hours is, 8.64 × 10⁶ J
Explanation :
As we are given that:
1 watt = 1 J/s
So,
100 watt = 100 J/s
Now we have to calculate the energy consumed by bulb in 24 hours.
As we know that:
1 hr = 60 min
1 min= 60 sec
So,
24 hr = 24 × 60 × 60 sec = 86400 sec
As, the energy consumed by bulb in 1 second = 100 J
So, the energy consumed by bulb in 86400 second = 86400 × 100 J
= 8.64 × 10⁶ J
Thus, the energy consumed by bulb in 24 hours is, 8.64 × 10⁶ J
