Illustrates the relationship between the voltages and currents present on opposite sides of a transformer.
The ratio of primary to secondary windings is 1:2, so the voltage measured on the secondary side is twice that measured on the primary. For current, the relationship is reversed: the current of the secondary side is half the current of the primary side.
(Note: The relationship between current and voltage on the primary side is not perfectly linear. This is because of the inductance of the primary coil. I set the inductance low so that the current would stabilize more quickly. )
