The one between your ears. I had observed once in a while a real light dimming turn on of the Variac I was using. So I set up a large current shunt and turned...
It has to do with chance. The current depends on the phase (time in ac cycle) when you throw the switch. It's a bit counter-intuitive, but the current is...
Hello Brenda, You can not use the composite video cables going from the outputs of the DVD and VCR to the TV for recording a TV program on the DVD. Instead ...
Let us assume first that the ammeter will measure the AC input current of the variac. As it wa mentioned 2 or 4 diodes will be needed to rectify the variac...
... Doesn't this approach rectify the voltage to DC before it gets to the load? That works great as long as the load will run on DC. It would seem to me that...
Richard, With a FWB feeding DC only to the shunt, AC still is present on the load. Your FWB is in SERIES with the load. AC in to the in side of the bridge, AC...
... Hi Richard, ... The load of the rectifier (half or full) is just the meter. Outside the box (rectifier and meter) voltages and currents are AC as before....
You must reverse one field relative to the other, exactly as I wrote!!! Reversing both and the motor runs in the same direction as before. Remember - IT'S...
Thanks Andy. For a layman as myself, just make sure the switch is connected the right way- everything else is easy....

That is not correct at all. I manage a dozen or so Yahoo Groups and all have been setup so as to allow attachments to messages. Attachments, however, are...
Correct. -I- forbid them. I find it rather arrogant to think your attachment should be sent to every last person in the group. It is also an efficient way to...
Hi Charles, Just get a double pole change over switch and cross over the normally open and normally close contacts on each other pole. Put the supply on the...
Maybe there is a protection circuit inside the battery pack which limits the current to something less than 4 amp? I can find no specification for discharge...
Hi, I want to run a 12Volt D.C. motor from the mains power. Has anyone got any idea what would happen if I connected the motor to my half wave thyristor power...
If your 12V DC motor doesn't draw too much power, I suggest you look at buying a used "wall wart". I paid $3 for mine and use it to power the motor which moves...
... I see the battery comes with a built in on-off switch. By any chance did you forget to turn the battery on? The other Howard [Non-text portions of this...
It will come to you not fully charged...charge it for 10 hours and give it a try... good advice howard. ... [Non-text portions of this message have been...
A battery rated for 6800 MAhr or 6.8 Ahr really means it will put out 680 mA for 10 hours. That is how they cheat. In one hour, It may put out only 5.2 Amps...
... Hi Jack, In theory your idea should work. For instance, when I was 25 years, after my graduation, I thought charging my 12V acid battery (60 AH) by using a...

First of all it's a real shock hazard. The motor insulation probably isn't designed to withstand 240VAC. There could be leakage to the case. If you DO try it,...
