So does that mean that i will save energy if i put them in series with no resistor, rather than putting them in parallel with a resistor? I know there's probably some advantages of putting them in parallel. But just in terms of energy, seems like putting them all in series should save a lot...

So I'm trying to build some electromagnets and i have some questions regarding how to power them. Imagine that i have a battery of 6 Volts and a coil with x gauge with y meters of wire that will equal 1 Ohm of resistance. So if i want to run it with 1 Amp of current i just put one 5 Ohm's...
