Question

A power plant has 4 tons of coal. a ton of coal produces 2,460 kilowatt hours of electricity. is this enough to power 9 light bulbs for a year? explain

Answer 1

Assuming 100 kw bulb

We'll start by figuring out how much energy in kilowatt-hours the light bulb uses per year. We multiply how much power it uses in kilowatts, by the number of hours in a year. That gives 0.1 kW x 8,760 hours or 876 kWh x 9 bulbs = 7884 kWh

 

The electricity produced by 4 tons x 2460 kWh/ton = 9840 kwh

Since the produced electricity is bigger so it is enough
