Load resistor is a function, not name.can you tell me another name for a load resistor, I've gone through the list of components trying to find one ?
Batteries don't hold current, as such, they hold charge. The charge is converted to current when it flows from the battery.well thanks for clearing that up , DerStrom8, I started to wonder how big the volts were in the battery whereas T now think it will only retain its volts longer because it is holding more current. it cant hold more volts !
If they both provide the same voltage, it won't make a difference, other than how long it runs before the battery discharges. The controller only takes the current it needs.but it would be interesting if I powered my motor controller with a 12v car battery instead of AA batteries
Thanks, I knew a battery must be holding something., i guess if Id thought more I may have realised its only current when it flows. A bit like if I had said to you that dam of water holds a lot of current... you'd decide to hang out with me a little less oftenBatteries don't hold current, as such, they hold charge. The charge is converted to current when it flows from the battery.

Perhaps the use of charge is not the best way to describe battery capacity. The number of electrons in a battery are basically fixed. The energy is stored chemically which generates the force (volts) to move the electrons in a loop from the negative to the positive terminal. Sort of like a pump moving water in a closed loop where the pump moves the same water around and around. So the battery capacity is given in ampere-hours which is a measure of how long the chemical energy lasts to keep the electrons moving............................
So the charge you speak of that is made up of electrons ? Can you speak about the capacity of a battery in electrons instead of amphours ? eg. this pattery has 500 grams of electrons, or this battery has 10 to the power of ? electrons ? ...........................
