"Usually," Tom observed, "the current would flow back to the source through the earth wire. But the simulation shows the impedance is too high." The primary goal of using this software is
Within two hours, the new rods were installed. The crew tested the resistance with a portable meter, and the reading matched the software’s prediction perfectly. The crew tested the resistance with a portable
