Pencil Resistors Science Project

In order for electricity to flow in a circuit, it must have a complete "loop," or path, to flow through. In a battery-powered circuit, this loop must connect the positive end of the battery (marked with a "+" symbol) to the negative end of the battery (negative is indicated by a "-" symbol, but this is usually not printed on the battery). This is called a closed circuit, as shown in Figure 1.

How Does an Electric ARC Furnace Work? Hunker

Arc furnaces melt down scrap and ore through the use of their graphite electrodes. When power is fed into the furnace, the electricity jumps between the two energized electrodes and into the neutral, grounded electrode. The high-voltage electric arcs created by these graphite spikes give off large amounts of direct and radiant heat that melt
