Any Electrical Engineers? Laptop inquiries
Tried googling.. but being up at the cottage.. the internet has become the interWAIT on 1X wireless dial up.
Basically.. I want to know wat wattage it would be from a 12V source to run something at 19V @ 3.46 Amps ( not including resistance and power loss etc.. ) |
3.46 amps at 19V gives you 65.74 watts.
|
And 5.48 amps at 12V
|
Amps (A) 3.46 x Voltage (V or E) 19=65.75 Watts (W)
Sounds like your trying to run a laptop |
Oh, DC Voltage x current (amps) = Power (watts)
|
so how much wattage at 12V would it take to equal 19V @ 65.75
|
You really can't make 12 volts = 19 volts. You need a converter (DC-DC)
|
Yes its running a laptop.. Long story short.. just wondering how much wattage/amperage it would draw on the car and or on the generator ( at the cottage ) to run the laptop..
|
The voltage "pushes" the amps or current. You have to have some way of coming up with the 19 volts first
|
If you are plugging your laptop into the car with a convertor, it will pull the same wattage.
