Question

An electric bulb of 100 watts is used for 3 days. Calculate the electrical energy
consumed per day.​

Answer 1

Answer:

100 x 3 isnt it?

so 300

Explanation:

Answer 2

Answer:

power of a object is defined as the electricity energy consumed per time

we know that,

100 wat = 0.1kw

and 1 day = 24hours aur 3 days = 72 hours

power is P = E/T

E = P×T

E = 0.1 KW × 72 HOURS

E= 7.2 kwh

hence the answer is electrical energy consume per day = 7.2 kwh
