Hello,
I know DC can increase and decrease its current and this is my problem.
I want the current of DC will just stay in one current. For example, I had 12 volts battery, if the voltage of battery is less than 12 volts then all the devices operated with it will go off.
Is there any such thing can done it?
P.S. Halogen lamp cannot be use in a series connection?
Anyway, why when I pull out one device on a parallel connection, the rest of devices in the parallel connection will become more stronger... (I mean if it's light, it becomes more brigther...) However, in AC (electric powered by electric company). no matter you add or remove, the power is still the same...
