The speed of an electron is a property of its own energetic nature while the speed of electrical motion is the rate an electron moves from point a to point b through resistance.
Energy is the work required for the function of a load, and resistance is the limiting factor of a load on the energy flow. Every household appliance is a resistor on the energy.
Ac current alternates the flow 60 times per second between two directions while direct current simply goes in one constant direction from a positive to a negative terminal.
Series: 14Ohm
Parallel: 3.4Ohm
