Source sentences:
text: Impedance (Ohms) represents the total resistance that the cable presents to the electrical current passing through it.
text: If at one frequency the impedance is really six ohms, and at another it's ten, Ohm's law will distribute these different frequencies differently to the circuit.
text: A speaker's impedance may nominally be eight ohms, but in reality it varies with frequency, starting high at low frequencies and falling.
