Impedance is specific to electronics and physics, used in professional or educational settings.

Technical Term

Impedance includes resistance and reactance (AC circuits), it's more complex than just resisting current.

Not Just Resistance

Impedance is measured in ohms, symbolized by the Greek letter Omega (Ω).

Unit of Measurement

In non-technical contexts, impedance metaphorically refers to hindrances or obstacles.

Metaphorical Use

When facing 'impedances', the focus is often on strategies to overcome them.

Overcoming Barriers

In non-technical use, impedance is an abstract idea not tied to physical objects.

Abstract Concept

 the last thing you do is repeat what you just said. You try and think of a different way of saying the same thing, or if you know the particular student and that student's cognitive style, then you might say it in a way that you think would have a good impedance match with that student.
