how can a 50 watt lightbulb use more energy than a 1000 watt oven?

Answer 1

Wattage is a measure of power, which is how much energy a device uses per second.

So, a 50-watt bulb could use more energy than a 1000-watt oven if the oven ran for 1 minute, while the bulb ran for more than 20 minutes.

Answer 2

1000 /50 = 20.

If one uses the oven for a time t, then he has to use the bulb for a time 20t, to have the same out put energy.

Therefore,

If we don't use the oven and use only the bulb, the bulb will consume more energy than the oven.

Or after using both for a brief time, simply switch off the oven and allow the bulb on for more than 20 times the brief time

Answer 3

the watt rating is based on one hour of use..
50 watt bulb means 50 watts for each hour of use
50 watt bulb would have to burn longer then 20 mins
for every min of the 1000 watt oven for that to be a true
statement,,
thats is ofcouse we assume the oven is being used at
full power

Answer 4

By leaving it on for more than 20 times the time the oven is on.

Answer 5

Light bulbs are continuous use, ovens are intermittent. Also, that is the ovens peak wattage.
