Sometimes. For instance, in circuit feeding a half-wave rectifier the impedance is much higher in one direction than the other.
But in general the impedances should closely match. IN fact, the electric system designed to have closely matched impedances.

In pure AC circuits , Resistance and Impedance are the same for both directions. But if you connect the AC power to a half-wave rectifier, the resistance or impedance will be different in one direction and another.

In a simple circuit (with a light bulb?) there should be little if any difference in either direction. However, in a circuit with one or more rectifiers, current is forced to go in only one direction and can produced pulsed DC. Also the whisker that touches a crystal in a crystal radio set allows current in only one direction (and serves as a rectifier).

No. The electricity is pulsing from side to side not actually travelling it.
