Power loss in transmission
In this task we will examine power loss in long wires and then see if we can reduce the power loss by using a transformer to step u and step down the voltage.
Using the variable power source make a simple series circuit with a switch and a globe.
Put the voltage setting on 4V AC. Make sure you are using the AC settings on the multimeter.
Measure the current and voltage. Across the globe and across the source.
