Impedance matching
Because transformers can step voltage and current to different levels, and because power is transferred equivalently between primary and secondary windings, they can be used to "convert" the impedance of a load to a different level. That last phrase deserves some explanation, so let's investigate what it means.
The purpose of a load (usually) is to do something productive with the power it dissipates. In the case of a resistive heating element, the...
