[simpits-tech] electrical ??

[Dave Hensley]

I need a little assistance with a power problem. I am trying to determine
the amount of amps I need going through the panels I have to light them up.
The panels are rated for 5vdc. I plugged in a 6vdc adapter which is putting
out 7.70v before anything is connected, measured with a mutlimeter. Then I
connected leads to the adapter and the panel, while leaving the leads for
the multimeter connected also. The volts in the multimeter dropped to 4.41v.
Next I connected only the meter to the panel set to measure resistance and
had a reading that fluctuated between .4 to .6, so I split the difference at
.5. So, using V=I*R formula, 7.70/.5=3.85. So, the lights are pulling almost
4 amps? Am I even close to having that right?

Obviously you guys are seeing that I know very little about this and am in
the process of learning. I am playing with the panel in an attempt to
understand the relationship of volts, current and resistance. If am I way
off at this point, I'll stop and do some more reading. I am just hoping I am
on the right track. :-)

Thanks!

Dave
