What voltage would you recommend with the 3 OHM...I hear people say what great battery life they are getting and Im not getting that. I am assuming that its because I have always used low resistence cartos and protank heads. Does higher ohm make a difference with battery life? I always thought if I had to up the voltage on them and that would drain the battery faster.
Many people use the ohm plus 2 formula. 2 ohm + 2 = 4 volts
Lower resistance actually use more
amps from the battery, which is what drains the battery. Standard/higher resistance use more voltage, but not as many amps. It's all about
Ohm's Law.
1.0 ohm and 3 volts = 3 amps (current) power drawn from the battery
2.0 ohms and 4 volts = 2 amps power drawn
3.0 ohms and 5 volts = 1.6 amps drawn
So the lower the ohm, the more energy that is drawn from the battery.
The electrons in a battery flow freely across the surface of wire coils. How much resistance that coil has determines how freely and fast the electrons are used.
Think of resistance as how water flows through a
narrow garden hose (high resistance) and a
wide garden hose (low resistance). More water flows freely in the wider water hose due to less resistance, so more water is used.
