If the load (ie, the resistance of the device being powered) is constant, then the only way for more current to flow through the load is to increase the supply voltage. That is: V = I * R. So for a constant load with constant supply voltage, the number of batteries in parallel does not affect the current. However, if the load is so small that the current pulled (V/R) is larger than the amount a single battery can supply (that is, the load resistance is close to the built-in resistance of the battery), the load will not see the full battery potential (it will be divided between the built-in R, and the load R). In this case, adding additional batteries in parallel will increase the voltage across the load, but it will never exceed the supply voltage (and thus, the current will never exceed V/R). -z -- # Zak Smith smithz@cae.wisc.edu (pgp) http://www.cae.wisc.edu/~smithz # Univ. of Wisconsin - Madison MSEE Student.
