Question

a water heater of 1500w is used daily for about 10 min then how many units of electricity does it use per month class 10I want urgently ​

Answer 1

Answer:

45,000 w or 46,500 w

Explanation:

Time used daily - 10 mins

Power used in 10 mins - 1500w

Power used in a day = 1500w

Days in a month = 30 or 31

Power used in a month = 1500 x 30 = 45.000 w or 45kw

OR

1500 x 31 = 46.500 w or 46.5 kw

FOR FEBRUARY -

Days in a month = 28 or 29

Power used in a month = 1500 x 28 = 42,000 w or 42 kw

OR

1500 x 29 = 43,500 w or 43.5 kw
