Which Materials are the Best Conductors? | Science Project
In order for electricity to flow in a circuit, it must have a complete "loop," or path, through which to flow. 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 (indicated by a "-" symbol, but this is usually not printed on the battery). This is called a closed circuit, as shown in Figure 1.
