    If you have a gizmo that turns a low voltage DC to higher voltage AC its

    called an inverter? What do you call a gizmo that turns low voltage DC to higher voltage DC

    My daughter has a Leapster handheld game with a a voltage setting of 9 volts 700 mA.?

    I bought a universal power cable for it so we don't have to waste batteries, but I noticed the adapter says it's 3-12 volts/ 600 mA. The voltage can be changed but the " mA " isn't the same. Can I still use the adapter?

    Grid Tied inverters? How we can get a constant 208 AC voltage out of inverter when

    input DC(insolation) is? varying? For my model, I am getting 500 VAC out of inverter but the grid line is at 208 volts. I am using current control scheme so the inverter is acting as current source but how do i manage to get a 208 volts out of inverter?

    Is it possible to get a constant voltage out of an inverter if the input

    DC is varying and what is the basic ? principle for it? How I can use a filter to have a constant output if input DC is varying?

    Can an AC adapter be modified to give AC voltage instead of DC?

    I tried removing the 2 diodes in one but a capacitor exploded. Should I remove the capacitor too or will that cause problems?

    Does analog mean the signal voltage is variable?

    Does digital mean the signal voltage is either high or low?

    how to make an AC to DC voltage tripler?

    I need to make a charger for my capacitor bank, and i think an AC to DC voltage tripler would do the trick. How would I go about making one? Thank you. =)

    How can a DC motor produce more torque with same voltage applied?

    While modeling a DC motor, http://www.engin.umich.edu/group/ctm/examples/motor/motor.html, what kind of variables should be changed to get the same voltage input and more torque on the shaft? (reasonable)

    What does negative voltage mean on my amp?

    I have one amp that turns on but will not put out any sound through the speakers, and one amp that works fine. I have a multimeter to test voltage, and when i hook it up to the speaker outputs on the working amp, it reads 0 volts (amp is powered on but no music is playing). When i hook it up to...

    Stall voltage of a permanent magnet DC motor?

    I've done a simple experiment to determine the motor resistance and back emf. The motor is connected in series with a shunt resistor to a variable voltage supply. From my knowledge, the motor voltage / motor current at stall is the motor resistor. However, when i stall the motor, the reading of...

    what voltage should a power supply unit create in a desktop pc?

    I have a desktop pc, I am trying to fix, it won't boot. I have checked the voltage ariving at the hard drive on an it is 6.5 volts, on my other working pc the voltage is 10.5 volts. Does this mean that the power supply unit is broken? What voltage should it produce?
