| Stephen was given two 6V batteries and one 12V light globe. He was told to connect the batteries and light globe in a circuit so that the light globe was glowing with maximum brightness. Stephen connected the circuit as shown on the right, and noticed how bright the globe was. | |
| Stephen noticed that the light globe was glowing as bright as if it was connected to one 6V battery. The challenge was not as easy as first thought. | |
| His brother Jonathon suggested that Stephen may wish to rewire the circuit to get more voltage across the light globe. He suggested the circuit shown on the right. | |
