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 = 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

 \sf \: E = P  \times t

  • 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
