1 Understanding Electrical TransmissionDemonstration C1 A Guide to the National Grid Transmission Model Demonstration C1 Transformers and power

2 Understanding Electrical TransmissionDemonstration C1 A Guide to the National Grid Transmission Model 1. What do you think might happen to the brightness of the LED if the step-up and step-down transformers are connected between the generator and the load unit?

3 Understanding Electrical TransmissionDemonstration C1 A Guide to the National Grid Transmission Model Make sure the generator is switched off each time you connect or disconnect components. Use leads with sheathed plugs to connect the transformers to each other. The step-up and step-down transformers are now used between the generator and load.

4 Understanding Electrical TransmissionDemonstration C1 A Guide to the National Grid Transmission Model 2. What has happened to the brightness of the LED? Why do you think this has happened? 3. Does this explain why transformers are used in the electricity transmission system?
