Want this question answered?
A Compaq nc6000 will run on ac power when the battery is dead. The battery is long lasting but it can be charged by using ac power.
i want to run a two ton ac with solar power
The power supply in most cars is DC. The alternator may produce AC power, but it is then run through a rectifier, providing DC power.
Are you planning to build a perpetual motion machine in which the power generated by an AC generator is used to run an AC motor which is used to run the same AC generator which provides it with power? Because that won't work. Yes, you can use a motor to generate electricity, and you can use electricity to run a motor, but the process is not 100% efficient and if you try to make it a closed loop, it will run down fairly quickly. So, what do we actually do? We use fuel to run an AC generator, or we use waterfalls or wind, or some other energy source, and then we use the power to run our motor.
power supply
If the power tool has brushes to bring the current to the armature it is classed as an universal motor. It will run on DC as long as the voltage is the same potential. On a welding machine the 120 volt receptacle is a DC output and the grinders, drills, etc that are plugged into it work fine.
its located in between the power steering pump and alternator when in doubt follow the ac lines that run to and from it
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
Yes, but the power you get out will be much less than the power you put into the motor.
No. check that the AC Power lead is plugged in and turned on. if the AC power lead is plugged in and turned on and still the battery is discharging, check that the AC power lead is working. this can be done with a multimeter. if the lead is faulty, replacements can be found. check the input power required by the laptop, as too much will blow the laptop up, and not enough will still make it discharge.
The Toyota Prius has electric AC, the gasoline engine will only run at idle with the ac when the battery drops below 50 %. The power steering is also electric. The same is also true for the Ford Escape hybrid. When you run the air conditioning, the gas engine will run until the a/c is fully charged then it will run off battery power. The downside of this is that you are deep cycling the batteries and shortening the life.
No. Some computer speakers require AC adapters, while others can run simply on battery power or USB.
