Resistor Help Needed

Electronics Forum | Thu May 20 09:29:02 EDT 2004 | Dilbert

Three LEDs, 3.5volts @.02amps each is 10.5volts. You said you calculated out an 82 ohm resistor so 82 ohms * .02amps is 1.64volts, I guess your going to use a 12volt supply. P=I*E =.02amps * 1.64volts =.033watts so a .25watt resistor will be fine

VCD 8 6241 loosing 5 volts supply

I am working on a vcd 8 with a problem of loosing the 5 volts supply. We have fitted a new supply that also provides the 15 volts. When we remove the connector on the power chassis for the 5 volts the power supply shows OK. When fitted the 5 volts is

Found the problem. Thanks for the pointers. I had set the voltage to 5.00 volts as it was reading 4.86 volts. I still had the problem. A slghtly burnt wire going into the spade connector on the back of fuse holder 12 (5 volts). The reason the voltage

How high a voltage are we talking , 240 volts, 4000 volts , 26000, volts 60,000 volts, 240 volts is easily done as we go up the scale insulation becomes a bigger problem and winding machines have to be much better in control of tension,also at higher

charging batterys via solar

What would happen if a 2 volt solar cell was hooked through a diode into to a 3.6 volt nicad (3xAA)? would it charge it at all? just a bit but never fully? would battery deliver 3.6 volt after charging? If left long enough would it charge fully?

charging battery with solar power?

If i hook a 5amp/12volt solar panel to a 6 volt lead acid battery, would it recharge it? is it as simple as hooking the two together? thanks,

4.85 V - 5.2 Volts. That is on the computer power inlet, Not the on the power supply. /Best Regards

Question on ANSI/ESD-S20.20-1999

1) I had downloaded ANSI/ESD-S20.20-1999 from www.eosesd.org web site. I am not clear whether section is correct. It states that " All process essential insulators that have electrostatic fields that exceed 2000 volts should be kept at a mi

MYData issue

There are no batteries in mydata magazines. This problem means your voltage is outside it's allowed range. In this case I think it's the 15 volts. If you open up the bottom of the machine and pull out the carriage you'll see a rectangular box that ho
