I got my lamp circuit to work and the light is glowing brightly.
The lamp is rated at 5v .06A and measures at 12 ohms.
So, before I plug the lamp in, the voltage at the lamp measures 6.7v.
Then I plug the lamp in, measure again and it shows 4v.
I don't get it.
Where did the 2.7 v go ?
Which leads me to a more general question in
Will the load try and get as much current or volts, as it needs, or will it try as best it can with what's available ?
Something similar is my cell phone charger. It has the ability to charge 2 devices so I asked a buddy that if I were charging 2 devices would they take twice as long. He said no.
I didn't continue the discussion as to asking that there must be a limit somewhere, in that I could not have an infinite number of devices.
And I am hoping someone here could point me to something that I can read that might explain it.
Thanks
