I have heard that you can add an external resistor to the positive in line, after estimating what the amps might be, to the meter and than use a formula which incorporates the ohms of the resistor and the amount of amps that the meter displays. Basically what is the formula for this and how do I go about it?

Some VRegs have the option to put a miriad of different negative voltages. Why would a circuit need this? Cant you just connect all negative and GND terminals (even thoughs that originated from a different +V source before its component(ie, LED) to a common GND ?

I need to step down +45v DC to +12v DC, with as little amps dissipated as possible. I was thinking about using a simple voltage divider circuit, but this dissipates too much heat (thus too much mA). I also looked into some VRegs from Linear and National, however the +12v does not need to be superbly regulated and using a VReg would waste power, and needs too many external parts.

I am looking to power a digital game camera that runs on a 6v battery. The big square type. I have added a solar charger however if the flash goes off to often in one day the battery is draned at a time when the solar charger isn't effective. My thought was to use two 6v in parallel or use a switch that would switch the power source before the battery is run down letting the other battery to be charged by the solar panel

No other cracks on property. Cracks in the area graded & built up, not tampted of a 40'x40'x4" concrete slab floor of a metal building. Hairline cracks started in 3 months & are expanding. Have contacted the builder but they avoid me. The NE corner seems to be settling & cracking. If you place a long level on a crack you can see the concrete is dropping. How serious is this?

The sub-contractor that did the clearing & grading missed the location by 2'. The concrete sub-contractors had to move the forms by hand digging them. The footings are 2' bigger. That is alot of concrete to shift. I have lost confidence in the grading contractor.

I believe that the northeast corner was not graded correctly and that corner is settling & cracking.

How far will it drop? How do I determine the extent of the damage? How do I have the problem corrected? Does it need to be redone or is it just cosmetic & a floor sealer would repair it? How do I negotiate with the contractor?

I met somebody who was in the know about the mercedes hydrogen powered car years ago, who told me the oil companies had paid a lot of money for them NOT to develop this technology. I just wondered if anyone knows whether we're likely to see hydrogen powered motors anytime soon?
