Basic reference transformer

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. )

hypnosb, I imagine this is actually pretty basic stuff for electronics nerds. But for novices like me, it's very useful to have a visual demonstration of the fundamental principles. I'm glad you found it helpful. Something else I realized recently, which helped me understand transformers better, is that they work on the same principle as mechanical gears. Simply substitute voltage for torque, and current for RPM. The number of windings in each coil is like the number of teeth on each gear.
