Electricity in our homes is 240V, why not transmit it at this voltage, rather than the 11,000V to 400,000V used on overhead power lines?

  • The answer is energy loss - this is much greater at low voltages, hence electricity is transported around the country at very high voltages
  • This apparatus is a ‘scaled-down’ version which demonstrates the principle at safe voltages
  • Touchproof, locking high voltage connectors
  • Clear lids allow pupils to see how it works and trace the circuit
  • Indicators for low and high voltage
  • Resistance wires can be connected to either the high or low voltage for comparison of lamp brightness and energy losses
  • By gripping the insulated cables, students can feel when and where the energy is being lost, mainly as heat
  • Complete with two boxes (transmit and receive), insulated resistance wires, two mounted SBC lamps and full instructions
