Answer:
- 446400 KiloJoules is the required energy.
Explanation:
Given:-
- Power of geyser ,P = 2000 W
- Time operated for daily ,t = 2hr =2×60×60= 7200s
- No. of days is 31 days.
To Find:-
- Electric Energy used by Geyser ,E
Solution:-
As we have to calculate the energy consumed by Geyser which is operated 2 hour daily . Electric energy consumed by Geyser in the month of January.
Electric energy is calculated by the Product of power of appliances & time used for it .
•E = P×t
where,
- E denote Energy Consumed
- P denote Power
- t denote time taken
Substitute the value we get
→ E = 2000 × 7200 × 31
→ E = 14400000 × 31
→ E = 446400000 J
As 1 Kj = 1000 J
Therefore, 446400000/1000 = 446400 Kj
- Hence, the energy consumed by Geyser in the month of January is 446400 KiloJoules.

Answer:
Given :-
- Power = 2000 W
- Time = 2 × 60 × 60 = 7200 sec
- No. of days = 31 days
To Find :-
Electrical energy
Solution :-
As we know that
- E is the Electrical energy
- P is the Power
- T is the Time
E = (2000)(7200)(31)
E = 446400000 J
In KJ
KJ = 446400000/1000 =446400 KJ
