A potência de uma lâmpada é medida em watts (W), e essa unidade já representa a quantidade de energia consumida por segundo. Portanto, uma lâmpada de 100 watts consome 100 joules de energia a cada segundo.
Em termos mais específicos:
-
1 watt = 1 joule por segundo.
-
Assim, uma lâmpada de 100 watts consome 100 joules de energia por segundo.
Então, se você quer saber a energia consumida por segundo, é exatamente 100 joules.

How far away would a lamp have to be for its light to take 2 s to reach your eyes?

Does a high watt bulb give more energy than a low watt bulb?
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
How much time is required for an operating 75 watt light bulb to dissipate 10 joules of energy?
To calculate the time required, you can use the formula Energy = Power x Time. Rearranging the formula gives Time = Energy / Power. Plugging in the values, Time = 10 Joules / 75 Watts = 0.133 seconds. So, it would take approximately 0.133 seconds for a 75-watt light bulb to dissipate 10 joules of energy.
How many miles does light travel in 17 minutes?
Light travels at a speed of approximately 186,282 miles per second. In 17 minutes, light would travel approximately 62,687,700 miles.
Could you emit the same amount of light energy per second which must emit more photons per second a source of red light or a source of blue light?
A source of blue light would need to emit more photons per second to produce the same amount of energy as a source of red light. This is because blue light has higher energy photons, so fewer photons are needed to achieve the same total energy output as red light, which has lower energy photons.

If you did not have fat in your diet how would it affect you?
You woud'nt have much energy and you would be very hungry. and you would want to sleep every second of the day, it is not a good thing.
What are facts about on the sun?
The age of the Sun is estimated to be: 4.6 billion years. Every 11 years sunspots 'explode. 100,000,000,000 tons of TNT' would have to be exploded almost every second to match the energy produced by the Sun every second.
How many photons of red light are produced every second?
That's really going to have something to do with the brightness of the source. Whatever color you want to talk about, the sun probably turns out more photons of it every second than a kitchen match does.
What would you use to transfer electrical energy into light and sound energy?
you flip a light switch on and it is turned into light energy
Why would physics be used to study light emitted by a star?
Light is a form of energy.
Does a high watt bulb give more energy than a low watt bulb?
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
What energy do mirrors release?
In a sense that would be light energy.
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
Which is more harmful to you a source emitting a million photons per second or a million neutrons per second?
Photons are light and while you do not specify the energy of this light (high energy light such as gamma radiation, X-Rays or UV light can be harmful) on balance a neutron source would be more harmful. This is because the neutrons have mass and on hitting you will tend to damage the atoms which make up your body.
Is there a light inside of the microwave when it is not in use?
No, when it is not in use, the microwave would not have a light on. Why would you want the light on when you are not using it and waste energy?
