A physics lab is designed to study the transfer of electrial energy from one circuit to another by means of a magnetic field using simple transformers. Each transformer has two coils of wire electrically insulated from each other but wound a round a common core of ferromagnetic material. The two wires are close together but do not touch each other The primary (1^(@)) coil is connected to a source of alternating (AC) current. The secondary (2^(@)) coil is connected to resistor such as a light bulb. The AC source produces on oscillating voltage and current in the primary coil that produces an oscillating megnetic field in the core. material. This in turn induces an oscillating voltage and AC curent in the secondary coil Students collected the following data comparing the number of turns per coil (N) , the voltage (V) and the current (I) in the coils of three transformers. |{:("Transformer","primary coil","Secondary coil"),(1,100 . 10V.10A,200.20V.5A),(2,100.10V.10A,50.5V.5A),(3,100.10V.10A,100.5V.20A):}| A 12 V battery is used to supply 2.0 mA of current to the 300 turns in the primary coil of a given transformer. What is the current in the secondary coil if N_(2) = 150 turns.
