PROCEDURE For You To Do In the first part of this activity, put together a step-up transformer (number of turns in the secondary coll is greater than the number of turns in the primary coil). In the second part of this activity, use the same coils to put together a step-down transformer (number of turns in the secondary coil is less than the number of turns in the primary coil.) Use the output of the interface to apply a voltage \\ across the primary coil in both transformer setups. Use the voltage sensor to measure the secondary output voltage V . Record V for two configurations: one with an iron core and one without an iron core. Use DataStudio to control the voltage output of the interface. Use the software to collect and display both V, and V . Finally, compare V to V PART IA: Computer Setup for Step-Up Transformer 1.

A transformer can be used to increase or decrease AC voltages. Transformers consist of two insulated coils of wire known as the primary and secondary coils. They are designed so that (nearly) all of the magnetic flux ; produced by the current in the primary coil also passes through the secondary coil. This may be achieved by wrapping the coils around a common iron core. The iron core strengthens the mag trates the magnetic flux inside core, minimizing flux leakage to the region outside the coils. Alternatively, the coils may be interwoven. An AC input voltage V, is applied across the primary coil. According to Lenz's law, the changing magnetic flux Ap/ Ar through the primary coil produces a back omf across the primary coil which balances the applied voltage, i.e. assuming that the resistance of the primary coil is negligible. By Faraday's Law of Induction, we obtain .= -N -= -VP. where /, is the number of turns in the primary coil. Assuming that all of the magnetic flux through the primary coil also passes through the secondary col and assuming that the resistance in the secondary coll is negligible, we obtain for the emf induced in the secondary coll ES = -NS AT -= -VS. where / is the number of turns in the secondary col and V. is the output secondary voltage. It follows that I N. > N . then V. > V and we have a stop-up transformer. If N.
