Morphology

transformer = transform (transparent) = transform + er

Standard agent/device nominalization from the verb 'transform'; the device meaning (changes electrical energy) directly follows from the base verb.

Etymology

Transformer comes from the parts trans- 'across' and form 'shape' or 'make', so it is something that moves something across and changes its shape. That's why an electrical transformer moves energy between circuits and changes the voltage or current.
