A 100W lamp is used for 4 hours daily. Find the electrical energy consumed in kWh in one month (30 days).
Answers (1)
Using the formula, $$
\text { Energy }= Power\times{ Time}
$$
Given data-
- Power (P) = 100W = 0.1 kW
- Time per day = 4 hours
- Total days = 30
Putting these values in the formula,$$
\text { Total energy consumed }= 0.1\times{4}\times{30}= 12kWh
$$
So, the lamp consumes 12 kWh (units) of electricity in a month.
