Question

how much electric energy is consumed by a 100 W lamp used for 6 hours everyday for 30 days

Answer 1

don't confuse by rate it's just time but per day is there that's why I wrote rate

Answer 2

Given:

power = 100w

time = 6hrs

days = 30days

To Find:

energy  consumed

Solution:

Power = 100w = 0.1 Kw

rate of consumption = 6 hrs / day

Energy = Power * rate * no of days

Energy = 0.1 * 6 * 30

Energy = 18 Kwh = 18 units

So, energy consumed in 30 days = 18 units.
