How many watts are in a laptop?

Answer 1

There are no 'watts' in a laptop.

A laptop, or any other electrical device uses electricity, and Watts measure the rate at which energy is used. Asking how many watts a laptop uses is like asking how many watts a light bulb uses. There are light bulbs that use a small fraction of a watt to those that use more than 1000 watts. As Watts measure energy consumption, it does not necessarily mean electricity: A person having a mass of 100 kilograms who climbs a 3-meter-high ladder in 5 seconds is doing work at a rate of about 600 watts.

It depends on the laptop as to how many watts it uses.

In electrical terms, one watt is the rate at which work is done when one ampere of current flows through an electrical potential difference of one volt.

When W=Watts; V=Volts; I=Amps; R=resistance in Ohms, then W = VI or W = I2R or E2/R

I have a netbook that uses a 19 volt, 1.5amp power supply. As Watts = Volts x Amps, it would appear that it uses 19 x 1.5 or 28½ watts. But that is only the power supply rating, The maximum the netbook uses is probably closer to half of that. The power supply is most likely very overrated. It operates nicely with the power supply when the battery is exhausted and being charged at the same time as being used.

Answer 2

The approximate Load of laptop is 100 Watts and if used 1 hour daily it will use approximate 3 units/ month

Answer 3

It is equippted with a 300 watt power supply

Answer 4

Laptop runs on a 10.8 to 20 volts DC depending on the manufacture and model. 10.8 Volts is the most common.

Answer 5

The wattage of a laptop typically ranges from 20 to 100 watts, depending on the model and usage. It is recommended to check the laptop's specifications or power supply for the exact wattage.

Answer 6

it takes 33 billion

Answer 7

3

Answer 8

600 watt
