The correct answer is
<span>
The 100 W bulb uses 2.5 times more energyIn fact, the power is the amount of energy used per unit of time. This means that the light bulb of 100 W uses 100 J in one second, and the light bulb of 40 W uses 40 J in one second, and if we compare the two numbers, we get
</span>
