Voltage is the dependent factor with Powercore. Knowing that 6 amps is the minimum current required (for HDPE 3/16" Rod), the voltage is adjusted to acquire 6 amps of current flow. The two main factors determining voltage are the amount current flow, and the length of Powercore. Higher current flow will require higher voltage. Longer lengths of Powercore will also require a higher voltage. Either an AC or DC power supply can be used, and the voltage and current requirements will remain the same. The graph below illustrates the voltage required to induce current flow from 1 foot (0.30 m) to 29 feet (8.7 m) of Powercore.
