Investigating the Number of Turns on the Secondary coil of a Transformer ` Method In this experiment I intend to investigate how altering the number of turns on the secondary coil of a transformer can alter the voltage output. To do this I will use a power pack with an alternating current with an expected voltage of around 2 volts. I will wire this up to a digital voltmeter in parallel to give me the exact voltage output of the supply and also to a primary coil of the transformer with 10 turns of wire wound around it. The primary coil will be wound around a laminated soft iron core (the lamination prevents eddy currents from developing) and this will provide the link between the primary and secondary coil. The secondary coil will have a number of turns between 1 and 50 but I will alter the number of turns in order to...
