Pro Tip 1/3Technical Term
Impedance is specific to electronics and physics, used in professional or educational settings.
The lecturer explained that impedance affects how electronic signals travel in a circuit.
Pro Tip 2/3Not Just Resistance
Impedance includes resistance and reactance (AC circuits), it's more complex than just resisting current.
In AC circuits, the impedance considers both the resistive and reactive components.
Pro Tip 3/3Unit of Measurement
Impedance is measured in ohms, symbolized by the Greek letter Omega (Ω).
The component's impedance was measured at 50 ohms.

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.
