1. The speed of an electron is spun around the center of the nucleus; the speed of electrical motion is dependent on the current, voltage, and resistance of the conductor.
2. Resistance is like the width of the walls to which electrons can pass through. A greater resistance, a smaller channel, the weaker the flow of energy.
3. DC current: energy moves in a single direction. AC current: energy periodically changes direction. Low-voltage alternating current is most famously used in USB charges, like one for a cellphone. DC current is used for most standard applications such as hair irons, coffee pots, lamps, etc.
4A: 34.29 ohms.
