Study model of electricity distribution

This model allows the study of the distribution of electricity through high voltage lines in homes. The 3 V power supply (symbolizing the general electrical network) first passes through a first set of analog voltmeter-ammeter, then through a transformer whose role is to increase the voltage (30 V) to ensure passage through the "high voltage" lines and avoid line losses. The voltage is visible on a second voltmeter at the end of the lines. The electricity then passes through a second transformer, this time with the role of voltage reducer; a second set of analog voltmeter-ammeter with a bulb allows observing the conservation of the initial voltage. Each of the 2 transformers has a switch to observe the effect of their presence, or absence, on the distribution of electricity.
