This spring is connected to neighbouring holes so that there is an electrical connection between wires pushed into adjacent holes. Fig (2) shows a section of the breadboard. Note that the holes are usually connected in groups of five, so that Figure 2: Diagram to show the connections between the holes in a breadboard. you can connect up to five wires at one point. The rows of holes at the top and bottom of the breadboard are normally used to provide high voltage and ground connections. The breadboards are provided with eight dummy terminals which allow you to connect a power supply to the circuit which you have constructed. 2 Multimeters A multimeter is the most useful measuring instrument which you will find in the laboratory. It allows you to measure voltage, current and resistance in both AC and DC circuits. Be aware that in AC mode, the multimeter will give a null reading when connected...
