The classic experiment for demonstrating the need for high voltage transmission has been assessed by CLEAPSS as being potentially lethal. As the experiment is now featured in the new Science curricula, we have developed a new, safe form of the experiment, which has the following features: Touch proof, locking high voltage connectors used throughout – it is virtually impossible to get an electric shock. The resistance wires can be connected to either the high or low voltage system for direct comparison of lamp brightness/energy losses. By gripping the insulated cables, students can feel when and where the energy is being lost, mainly as heat.
SEM1000 comes complete with two boxes (transmit and receive), insulated resistance wires, two mounted SBC lamps and full instructions.
