∙ 12y agoIt takes the same amount of current, regardless of how long it is energised! Time is irrelevant to this question! The value of that current depends on your supply voltage. If you live in Europe, that is probably 230 V; if you live in North America, that will be 120 V. You can work it out, yourself, by rearranging the following equation:
P = V I
where: P = power, V = voltage, and I = current
Of course, you don't pay for the current drawn by a lamp. So, if your question actually mean how much energy (which you do pay for!) the lamp will consume in 30 s, then you need to work out the number of kilowatt hours it has used in that period. To do this, you need to convert the power of the lamp, in watts, to power in kilowatts, and the time in seconds must be converted into hours. You then multiply them together.

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.
How much time is required for an operating 75 watt light bulb to dissipate 10 joules of energy?
1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds
How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second
Where do you find a watt?
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
Compare and contrast a 60 watt and 100 watt light bulb?
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
How much work does a 100-watt light-bulb do when it is lit for 30 second?
3000 joules(J)

How much work does a 75 watt bulb do?
In the sense of 'work' as force moving through a distance, a light bulb does none of that. But in the sense that mechanical work is equivalent to energy in other realms, the 75-watt light bulb consumes 75 joules of electrical energy every second, and radiates 75 joules per second of energy in the form of light and heat.
How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second

Is a watt a light bulb?
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
Compare and contrast a 60 watt and 100 watt light bulb?
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
What is the minimum watt of a light bulb for night reading?
40 watt light bulb. This is obvious. Go do an experiment. -_-
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.
What is the highest watt light bulb that there is?
the highest light bulb is 100
